comments on the ludicrous recent decision by the Supreme Court regarding the denial of the right to DNA testing of crimes by "convicted" people...the quality of mercy is severely strained...jg From the New York Times, June 21, 200, Letters Section

Unfair Denial of DNA Tests

To the Editor:

At its core, due process of law is about fairness, reasonableness and justice, none of which was served by the Supreme Court’s decision to deny a request for new DNA testing to challenge a rape conviction (“Unparalleled and Denied,” editorial, June 19).

The court wrongly deferred to the other branches of government in supporting its decision, as evidence so potentially overwhelming as DNA testing rises well above any technical legal argument the court’s majority used to support its decision. The court should never shrink from its duty to vigorously enforce due process in whatever context it arises.

Moreover, if the criminal justice system failed, as it may have here, not only was the wrong man jailed but also the guilty have remained free.

To the Editor:

Re “Court Rejects Inmate Right to DNA Tests” (front page, June 19):

The five hard-line conservative justices on the Supreme Court have once again acted to curtail justice in our country. There is no reason, if DNA evidence can exonerate an innocent convict, that the simple test ought not be given.

Chief Justice John G. Roberts Jr.’s argument that such a right would overthrow the established criminal justice system makes absolutely no sense, and only reveals his anxiety to uphold the institution of justice rather than its spirit.

The aim of the justice system is to establish the facts of each case. Therefore, the opposite of Justice Roberts’s argument is true: far from overthrowing the system, DNA testing would affirm it, whereas to refuse to examine pertinent DNA evidence would amount to a miscarriage of justice.

Anyone else feel that life became more special once leaving religion? (self.atheism)

submitted by HotMustard

When I was religious, Mormon to be precise, I believed that I was created by God and given a this life as a test and an exercise in free will. As soon as I left the Mormon church I had to deal with the idea of life most likely being a pointless event of random chance with no inherent meaning whatsoever. Coming from a belief system which asserted that there was a loving deity purposefully creating everything that I would spend eternity with in infinite bliss, this was a very jarring idea that didn't immediately sit well with me.

That is, until I began to read authors like Carl Sagan and learn more about the unfathomable awesomeness of the universe. It hit me like a supernova that it doesn't matter if there's someone else watching from above and putting some purpose in my time here. I have a truly priceless gift, no matter how infinitesimally short, of life in this amazing universe where I can think and feel and be. I can connect and share experiences with other people who also enjoy this chance existence. Just because my life didn't come prepackaged with a meaning doesn't mean that it's worthless; I don't believe nature has any inherent purpose and yet I feel that it has a beauty nonpareil, untouchable by anything we can create. I can give my life whatever meaning I want it to have, and no matter what happens in it or what I do with it it will be the greatest thing I can be certain that I will ever truly experience.

Hopefully that doesn't sound too corny, but I know there both people out there who struggle with the idea of life not having a religiously-given meaning and people who feel that atheism has nothing positive to offer, and to them and anyone else I just wanted to take a moment to share that my life has never been as special to me as it was once I left religion.

Next, an article suggesting cultural variations within the same species. Not so long ago, we actually debated whether culture even existed in n-human species, now some whales have blown that oldy moldy idea out their blowhole...jg

Hidden Whale Culture Could Be Critical to Species Survival


Though it sounds at first like a marine biologist’s take on political correctness, respecting the cultural diversity of whales may be essential to saving them.

Scientists are accustomed to thinking of whale populations in terms of genetic diversity. But even when they share the same genes, groups of whales can live in very different ways, raising the possibility that species might be saved even while individual cultures vanish. The tragedy of cultural extinction aside, cultural diversity may sustain the long-term health of Earth’s cetaceans.

“We have no idea what’s going on. As we mess up the world, it goes off in all kinds of weird directions,” said biologist Hal Whitehead of Dalhousie University in Nova Scotia. ”The more diversity that’s out there, both genetic and cultural, the more whales can deal with it.”

That whales could even have culture is a relatively new scientific proposition. It was not unil the late 1960s that recordings of humpback whale songs provided a glimpse of the unexpectedly complicated and beautiful world of cetacean communication. The songs don’t appear — for now — to reach the level of language, but they’re clearly a form of learned communicative behavior common across the cetacean realm. And as researchers spend more time with whales, they’re realizing just how much their learned behaviors differ.

One of the best-known example of marine culture comes from killer whales (which, technically, are dolphins, but they’re mentioned in the same breath as whales by biologists). Pods of killer whales have highly varied dialects and ways of life, even while sharing the same habitat — the aquatic equivalent of a neighborhood populated by two different ethnic groups.

Over the last decade, two pods found off North America’s west coast and known to researchers as the Northern and Southern residents became the focus of an international conservation battle. Scientists showed that the pods had different dialects and feeding habits. The Southern Residents, their numbers at a fraction of historical levels, often ranged south through Puget Sound and into waters off the California coast. They’re more threatened than their Northern counterparts by shipping collisions and depleted salmon populations.

In 2004, Canada’s environmental officials declared the Southern Residents both distinct and endangered, but U.S. officials insisted on treating the two pods as a single, genetically similar and unendangered group. The next year, following outrage among scientists and environmentalists, the United States acknowledged the Southern Residents as unique and endangered.

Their decision was promising, but cultural considerations are otherwise absent from U.S. government conservation plans and the agenda of the International Whaling Commission. To some extent, the absence reflects the state of cetacean science. Most species have not been extensively studied at the cultural level. But with pollution, noise, global warming, overfishing and intermittent hunting threatening the recovery of creatures nearly hunted to extinction by the early 20th century, it might be time to expand the focus.

Who is Anonymous?

  • Anonymous is a cultural phenomenon which began on internet image boards. Many such boards require no registration for posting, and every poster remains anonymous. This format of communication is inherently noisy and chaotic. However, the unprecedented openness made possible by such boards has nurtured the appearance of a unique and persistent culture.

    We are a collection of individuals united by ideas. You likely know Anonymous, although you don't know exactly who we are. We are your brothers and sisters, your parents and children, your superiors and your underlings. We are the concerned citizens standing next to you. Anonymous is everywhere, yet nowhere. Our strength lies in our numbers. Our will as a whole is the combined will of individuals. Our greatest advantage is a knowledge of the fundamentals we share as human beings. This knowledge is a fruit of our anonymity.

    Anonymous has left its mark on society more than once. Previous Anonymous projects have resulted in the closing of the white-supremacist radio show produced by Hal Turner, and the criminal prosecution of Canadian pedophile Chris Forcand. Anonymous has been called a "Cyber Vigilante Group" by The Toronto Sun and Global News, though in reality we are much more than that.

    We are Anonymous. You can be Anonymous, too. Together, we can shape society.

Don't Leave It Lying Around the House, October 23, 2008
This book should never be left where it could fall into the hands of children. Recurrent themes of bloody violence, murder, racism, incest and rape are dealt with extremely irresponsibly. Horrific events are presented as justified by circumstances and as solutions to petty wrongs.

Worse than the depictions in the book are actual historic examples of such depictions being used to justify the worst kind of degradation and humiliation that humans have ever been forced to endure. These acts are not just inspired by this book, but characters in the book urge its readers to follow its example. Worst of all, however, is that, despite this book's obvious lack of coherent logic or sense, it inexplicably possesses a following of people that somehow find comfort in its horror.

No doubt about it, the horrific images, and lack of intelligent discussion of those images, contained in this book makes it entirely unsuitable for children, or sensible adults.

It is very doubtful that a book that meanders so terribly, and contradicts itself so often, is truly inspired by a deity. What you will read in here can be found in other mythologies. There is nothing truly unique about it.

Upon close scrutiny, we discover that the content of Bible is a compilation of historically and archaeologically unsupportable Myths such as Noah's ark, Abraham, Joseph, David, Solomon, etc.

Homeopathy kills

[Note: This post may upset some people. It damn sure upset me. If you are easily upset by pediatric medical stories that do not end well, then you might want to skip reading this. The title alone may be all you need to know.]

Homeopathy is the antiscientific belief that infinitely diluted medicine in water can cure various ailments. It’s perhaps the most ridiculous of all "alternative" medicines, since it clearly cannot work, does not work, and has been tested repeatedly and shown to be useless.

And for those who ask, "what’s the harm?", you may direct your question to Thomas Sam and his wife Manju Sam, whose nine-month-old daughter died because of their homeopathic beliefs.

The infant girl, Gloria Thomas, died of complications due to eczema. Eczema. This is an easily-treatable skin condition (the treatments don’t cure eczema but do manage it), but that treatment was withheld from the baby girl by her parents, who rejected the advice of doctors and instead used homeopathic treatments. The baby’s condition got worse, with her skin covered in rashes and open cracks. These cracks let in germs which her tiny body had difficulty fighting off. She became undernourished as she used all her nutrients to fight infections instead of for growth and the other normal body functions of an infant. She was constantly sick and in pain, but her parents stuck with homeopathy. When the baby girl developed an eye infection, her parents finally took her to a hospital, but it was far too late: little Gloria Thomas succumbed to septicemia from the infection.

Thomas and Manju Sam were convicted yesterday of manslaughter in Australian court. As a parent myself I cannot even begin to imagine the pain they are going through, the anguish and the emotional horror. But let us be clear here: their belief in a clearly wrong antiscientific medical practice killed their baby. Homeopathy doesn’t work, but because they were raised in an environment that supports belief in homeopathy, they trusted it. They used it, and they rejected real, science-based medicine. And their daughter suffered the consequences.

And suffer she did. The accounts of the pediatricians who tried too late to help little Gloria Thomas are simply harrowing.

Every time I hear about something like this — a baby dying due to "alternative" medicine, or the lies and disinformation from the antivaccination movement, or some other belief system that flies in the face of reality — a little bit of me dies as well. I held my daughter shortly after she was born, and I would have done anything to protect her, and that included and still includes protecting her against people who fight so adamantly against reality.

The reality is that the antivaxxers’ work will result in babies dying. The reality is that belief in homeopathy will result in more babies dying. The reality is that denying science-based medicine will result in more babies dying.

And I know these words will fall on many deaf ears. And I will guarantee the comments to this post will contain many loud and irrational arguments supporting homeopathy and the antivaxxers. I’ve seen it before, and I know that many of those people are completely immune to reason and logic. And if you wonder what might wake them up, the answer may very well be nothing. Just read what Gloria Thomas’ father — the man just convicted of the manslaughter of his own daughter — had to say:

But even after Gloria died, Thomas Sam adhered to his belief that homeopathy was equally valid to conventional medicine for the treatment of eczema.

He told police: “Conventional medicine would have prolonged her life … with more misery. It’s not going to cure her and that’s what I strongly believe.”

He and his wife face 25 years in jail, where they will have plenty of time to rethink their convictions.

Kung Fu is Dead!

Actor David Carradine found dead

American actor David Carradine has been found dead in a Bangkok, Thailand, hotel, according to his personal manager, Chuck Binder.
David Carradine became famous in the 1970s after starring in the television series "Kung Fu."

David Carradine became famous in the 1970s after starring in the television series "Kung Fu." Binder said Thursday that the death is being investigated but could provide no other details. Carradine's death was "shocking and sad. He was full of life, always wanting to work ... a great person," Binder said, according to People magazine.

Carradine, who became famous in the 1970s when he starred as traveling Shaolin monk Kwai Chang Caine in the television series "Kung Fu," was 72. Modern audiences may best know him as "Bill" in Quentin Tarantino's "Kill Bill" films. He earned a 2005 Golden Globe nomination for his role in the second movie in the two-part saga. iReport: Share memories of David Carradine

You can read the rest of the obit here

It may be hard for some of you to imagine, but I watched Kung Fu religiously when I was a little kid, and I took it in deeply.

The spiritual side of a
Buddhist Monk, with the kick-ass side of an American Wild West hero. I know he was just an actor, but to me he was Kwai Chang Caine.

As mentioned in the article above, he was also Bill in "Kill Bill," but I'll always remember him as the gentle monk who never looked for violence, but when it came his way, he took care of business.

It introduced me to both
Buddism and the martial arts, and I started studying Judo right after that, which I practice to this day.

Namaste, David, and I hope your next incarnation brings you a better life. jg

Well, back after a bit of a hiatus, for reasons obvious from my last post. Requiescat in pace et in amore, pater (rest in peace and love, father).

So, to start off again, here's a cool article from Wired Magazine online. Turns out we had a few more cradles of civilization than we thought, and, if you remember that Mesoamericans discovered agriculture all on their own (here is good, and here too, for more info), if not as early as those in the Middle East or Far East, it was still an independent invention...

Science Revises Civilization’s Creation Story
By Alexis Madrigal Email Author

1568512864_6e394634e6_b

The Middle East, near where the Tigris meets the Euphrates, has long been considered the “cradle of civilization,” but a series of new studies indicate that Chinese river valleys represent a second spot for the emergence of agriculture.

Genetic studies, using DNA from charred seeds gathered at the world’s first farms, are slowly rewriting the long-told story of how “civilization” began. In an essay in Science this week, Cambridge archaeologists Martin Jones and Xinyi Liu argue that millet spread west long before the Middle Eastern crops (wheat and barley) spread east.

More generally, they say that the Agricultural Revolution took place so slowly that it was probably imperceptible to those humans experiencing the transition. Early farmers continued to harvest wild rice varieties and the percentage of domesticated rice species that they the percentage of domesticated rice harvested versus wild rice increased just a few percent in a human lifespan.

“Rather than a revolutionary shift from hunter-gatherers to farmers in a few human generations, the evidence now suggests that many generations of ‘affluent foragers’ combined the gathering of wild fruits and nuts with the gathering of cultivated cereals,” write co-authors Martin Jones and Xinyi Liu.

Op-Ed Columnist - Our Greatest National Shame

Published: February 14, 2009

So maybe I was wrong. I used to consider health care our greatest national shame, considering that we spend twice as much on medical care as many European nations, yet American children are twice as likely to die before the age of 5 as Czech children — and American women are 11 times as likely to die in childbirth as Irish women.

Yet I’m coming to think that our No. 1 priority actually must be education. That makes the new fiscal stimulus package a landmark, for it takes a few wobbly steps toward reform and allocates more than $100 billion toward education.

That’s a hefty sum — by comparison, the Education Department’s entire discretionary budget for the year was $59 billion — and it will save America’s schools from the catastrophe that they were facing. A University of Washington study had calculated that the recession would lead to cuts of 574,000 school jobs without a stimulus.

“We dodged a bullet the size of a freight train,” notes Amy Wilkins of the Education Trust, an advocacy group in Washington.

So for those who oppose education spending in the stimulus, a question: Do you really believe that slashing half a million teaching jobs would be fine for the economy, for our children and for our future?

Education Secretary Arne Duncan describes the stimulus as a “staggering opportunity,” the kind that comes once in a lifetime. He argues: “We have to educate our way to a better economy, that’s the only way long term to get there.”

That’s exactly right, and it’s partly why I shifted my views of the relative importance of education and health. One of last year’s smartest books was “The Race Between Education and Technology,” by Claudia Goldin and Lawrence F. Katz, both Harvard professors. They offer a wealth of evidence to argue that America became the world’s leading nation largely because of its emphasis on mass education at a time when other countries educated only elites (often, only male elites).

They show that America’s educational edge created prosperity and equality alike — but that this edge was eclipsed in about the 1970s, and since then one country after another has surpassed us in education.

Perhaps we should have fought the “war on poverty” with schools — or, as we’ll see in a moment, with teachers.

Some education programs have done remarkably well in overcoming the pathologies of poverty. Children who went through the Perry Preschool program in Michigan, for example, were 25 percent less likely to drop out of high school years later than their peers in a control group, and committed half as many violent felonies. They were one-third less likely to become teenage parents or addicts, and half as likely to get abortions.

Likewise, the KIPP program, the subject of a fine book by Jay Mathews, has attracted rave reviews for schools that turn low-income students’ lives around.

There are legitimate questions about whether such programs are scalable and would succeed if introduced more broadly. But we do know that the existing national school system is broken, and that we’re not trying hard enough to fix it.

“We have a good sense from the data where there are big opportunities,” notes Douglas Staiger, an economist at Dartmouth College who studies education.

The hardest nut to crack is high schools — we don’t have a strong sense yet how to rescue them. But there’s a real excitement at what we are learning about K-8 education.

First, good teachers matter more than anything; they are astonishingly important. It turns out that having a great teacher is far more important than being in a small class, or going to a good school with a mediocre teacher. A Los Angeles study suggested that four consecutive years of having a teacher from the top 25 percent of the pool would erase the black-white testing gap.

Second, our methods to screen potential teachers, or determine which ones are good, don’t work. The latest Department of Education study, published this month, showed again that there is no correlation between teacher certification and teacher effectiveness. Particularly in lower grades, it also doesn’t seem to matter if a teacher has a graduate degree or went to a better college or had higher SATs.

The implication is that throwing money at a broken system won’t fix it, but that resources are necessary as part of a package that involves scrapping certification, measuring better through testing which teachers are effective, and then paying them significantly more — with special bonuses to those who teach in “bad” schools.

One of the greatest injustices is that America’s best teachers overwhelmingly teach America’s most privileged students. In contrast, the most disadvantaged students invariably get the least effective teachers, year after year — until they drop out.

This stimulus package offers a new hope that we may begin to reform our greatest national shame, education.

Former Vice President Al Gore addresses the American Association for the Advancement of Science.
Former Vice President Al Gore addresses the American Association for the Advancement of Science.

From former Vice President Al Gore’s speech to a slew of fascinating presentations, the annual meeting of the American Association for the Advancement of Science in Chicago, Illinois, was a whirlwind tour of innovative ideas. Here are some highlights of what we did:

Saw Gore’s presentation: Given that pop-culture conferences have concerts as their evening highlights, it makes sense that the AAAS would have America’s climate-change rock star — who recently won a Grammy, no less — to get people on their feet. More than a thousand scientists, journalist, educators and students greeted Gore with a standing ovation as he took the stage.

In his speech, Gore identified a common thread between global warming, our national security and the world financial meltdown — our “absurd” dependence on carbon-based fuels. When you pull on the thread, he said, “then all three of these crises can begin to unravel.” The solution: shifting to an infrastructure based on fuels that are free, such as solar and wind power, and bolstering the science of clean and sustainable energy.

Gore seemed optimistic about Obama’s appointments to the Cabinet and the direction our country is taking to address the issue of climate change, which he called “a historic struggle.” He emphasized the importance of us all working together as a species in order to prevent further threats to the entirety of human civilization.

Through a series of slides, which included the most recent scientific findings on climate change, Gore communicated his “inconvenient truth” to the audience while urging scientists to get more involved in their communities. He also called on scientists to get involved in politics, to speak out as “civic scientists” and to “find ways to communicate the truth.” He concluded by saying, “Keep your day job, but start getting involved in this historic debate. We need you.”

P.S. Gore uses an iPhone, too — he had to turn it off during the speech.

Learned about stem cells: Bone marrow is one important source of adult stem cells, researchers say. And did you know that humans make 10 billion red blood cells every hour of every day? Dr. Will Li of the Angiogenesis Foundation talked about the potential of endothelial progenitor cells in the marrow for treatments of conditions such as diabetes.

Got in touch with our emotions: People commonly feel better by writing their feelings down, and now scientists are beginning to understand why. Brain-imaging studies indicate that putting your feelings into words has the effect of regulating emotions, said Matthew Lieberman of the University of California, Los Angeles.

Became kissing experts: Researchers presented their findings on the hormones involved in kissing, and the role of kissing in beginning (or ending) relationships. Full story

More from the conference: learn about a face transplant patient, think about foods of the future, and ponder Darwin’s connection to Buddhism.

Obama on Teaching Evolution


I believe in evolution, and I support the strong consensus
of the scientific community that evolution is scientifically
validated. I do not believe it is helpful to our students to
cloud discussions of science with non-scientific theories like
intelligent design that are not subject to experimental
scrutiny.

America Must Improve Scientific Understanding

By BGH

We are failing.

In a modern society increasingly ruled by scientific and technological advances, too many people in America are turning an ignorant eye toward the sciences, even to the extent of dismissing the value of a generic passing understanding.

Why? Is it too easy to focus on 'American Idol' and too difficult understand the difference between planetary revolution and rotation, or a virus and an infection.

A general science comprehension is not a matter of memorizing equations, chemical formulas or even constellations, it is a matter of understanding the scientific method, an awareness that the best way to understand the universe is through critical analytical methods, and that without science nearly all of the comforts and infrastructure we enjoy in our daily lives, most likely would not exist.


The ignorance is phenomenally stunning and frustrating at the same time. Hospitals are facing increasing difficulties fighting super-strains of bacterial infections because antibiotics have been over requested/over prescribed for every little sniffle and every little cough.

With little knowledge of the distinction between antivirals and antibiotics, patients will fall ill and aggressively request an antibiotic for what is more often a virus and not an infection, many doctors give in because of backlogged caseloads and patient persistence. The 'bugs' that were once controllable and curable with conventional antibiotics have now evolved a resistance.

It seems nearly every year, one of my co-workers will make the unfortunate claim that they got the flu after getting a flu shot (you cannot, it is a dead virus contained in the shot), then this simple correlation/causation fallacy leads them to abstain from the shot the following flu season. Additionally, there are great misunderstandings among the general population of what the 'flu' exhibits as symptoms, and many times the common cold is
confused for influenza.

Then, there exists a continual questioning of funding for NASA. A common chorus among those who poorly understand science, "why are we spending millions of dollars to send robots into space or another planet when we have so many problems on earth?" This comment is extremely frustrating and most people simply do not understand the benefits garnered from the space program. Along with a greater understanding of other planets, we also learn more about our own.

Additionally, we have gleaned every-day technological advances in our homes, our work, the medical facilities and in our cars from space engineering and technology. The devices with which you text your friends, navigate a car with pinpoint accuracy and view breaking news from around the world would be most likely non-existent without the advances made since we first launched rockets into space.


But, the problem is so much more than appreciation, it is almost a complete incomprehension for many people when it comes to science and methods by which knowledge is garnered. Appreciation will not come from memorizing facts or formulas for a standardized test, it is fostered through inspired teachers who love the field and are excited to pass the knowledge on to others.

Science is not difficult when presented an interesting manner where we can relate it to our every day lives, too many people just do not see the connection.

From the Bad Astronomy blog (an awesome science blog, BTW) jg

Obama on evolution

Thought from Kansas (you do read that, don’t you?) has a post up with a quotation from Obama about evolution, taken from the York Daily Record (emphasis mine):

Q: York County was recently in the news for a lawsuit involving the teaching of intelligent design. What’s your attitude regarding the teaching of evolution in public schools?

A: “I’m a Christian, and I believe in parents being able to provide children with religious instruction without interference from the state.

But I also believe our schools are there to teach worldly knowledge and science. I believe in evolution, and I believe there’s a difference between science and faith. That doesn’t make faith any less important than science. It just means they’re two different things. And I think it’s a mistake to try to cloud the teaching of science with theories that frankly don’t hold up to scientific inquiry.

While I disagree with Obama a bit (obviously, I wouldn’t put faith on equal footing with science), his attitude is pretty good, and for a politician running for President it’s phenomenal. Clinton was clear on this issue as well. And both are far, far better than the mealy-mouthed equivocating McCain made on this topic.

This is just another of the 270+ planets found so far outside our solar system. Although, as the article from Wired Magazine mentions, it's probably too big of a planet for any form of life like we find on Earth, the chemical composition strongly suggests signs of life. In fact, scientists know of no other way such chemicals could arise naturally, without the help of living things. More evidence we are not alone…jg


Molecular Basis of Life Discovered on Extrasolar Planet

NASA released this rendering of HD 189733b, an extrasolar planet more than 60 light years from Earth, which has the organic molecule methane in its atmosphere.

Scientists using the Hubble Space Telescope have for the first time found the telltale signature of methane, an organic molecule, in the atmosphere of a planet outside our solar system.

Methane is one of the chemicals of life, an organic compound in the class of molecules containing carbon. However, no life is likely to exist on the large, gaseous planet known as HD 189733b. Its daily temperatures can reach 1,340 degrees Fahrenheit.

"These measurements are a dress rehearsal for future searches for life," said Mark Swain, a scientist at NASA's Jet Propulsion Laboratory and the lead author of a new study that appears in Nature tomorrow. "If we were able to detect [methane] on a more hospitable planet in the future, it would really be something exciting."

The latest atmospheric observation is a clear step toward understanding planets across the galaxy. Since the discovery of the first so-called exoplanet 13 years ago, scientists have been able to glean little about the 270-plus known extrasolar planets. Even rough sizes and masses have been calculated for a mere 30 of those planets. It is only in the last year that scientists have begun to characterize the conditions on these planets, like their surface temperatures, and as in this case, the chemical composition of their atmosphere. Such findings not only shed light on other solar systems, but also on our own.

"The work ties these extrasolar planets to our own [solar system's] planets. We can start to understand these giant planets as a class of astronomical objects," said Jonathan Fortney, an astronomy professor at the University of California, Santa Cruz. "You can start to say now that the Jupiter-like planets in other solar systems seem to be similar to our own Jupiter."

HD 189733b, a so-called "hot Jupiter," located 63 light years away, has proven a boon for scientists studying exoplanets. Its large size and proximity to its star mean that it dims the star's light more than any other known exoplanet. Combine that with its home star's high brightness, and scientists find that the system creates the best viewing conditions of any known extrasolar system.

"Its orbit is such that it's just aligned with Earth, so you see as the planet comes in front of the star and it obscures a bit of the light," said Gilda Ballester, a planetary scientist at the University of Arizona.

At different wavelengths, every atom and molecule has its own telltale footprint, so scientists can convert what are known as absorption spectra into the chemical composition of the object they're looking at.

The technique, known as spectrography, will remain the main scientific technique for learning about exoplanets into the future, Fortney said, with planets that could support life.

"These techniques are going to be the same techniques we're using for even smaller exosolar planets, for example terrestrial or Earth-like planets," said Seth Redfield, a Hubble postdoctoral fellow at the University of Texas at Austin, who previously identified sodium in HD 189733b's atmosphere.

Redfield noted that merely studying exoplanets many times the size of Earth was pushing the envelope of current science.

"Twenty years from now, we'll be able to do this for superearths," Fortney said. "We'll be able to see methane in the atmosphere of an Earth-like planet."

To do so, however, astronomers will need new tools. Swain's team used Hubble's Near Infrared Camera and Multi-Object Spectrometer to capture rough spectrographic data. They were forced to use the low-resolution tool because the dedicated instrument for spectrography -- the Space Telescope Imaging Spectrograph -- broke in 2003, Redfield said.

"The STIS spectrograph would get resolutions several orders of magnitude higher than the tool they used," Redfield said.

He said NASA was planning to try to fix the tool in late summer of this year, and that access to the tool could lead to new discoveries. In the meantime, scientists will keep plugging away, revealing the properties of planets dozens of light years away, molecule by molecule.

"We know so little observationally about these planetary atmospheres that any sort of measurement is tremendously exciting," Redfield said.
