But because the planet is also in a much closer orbit to its star than Earth is to the Sun (Just over a million miles away compared to Earth’s 93 million miles, with a year of just 38 hours), its surface temperature is way hotter: an average 446 degrees fahrenheit, according to estimates from the Harvard-Smithsonian Center.
That means that the water on the surface of GJ 1214b is doing weird things besides turning into steam.
“The high temperatures and high pressures would form exotic materials like ‘hot ice’ or ‘superfluid water’, substances that are completely alien to our everyday experience,” Berta explained.
This Ezra Klein post has everything: a link to news of Newt Gingrinch’s upcoming “visionary” speech on the U.S. space program and a ranking of the planets, moons, and exoplanets by habitability. Watch out, Gliese 581gians! We’re coming for you.
* ‘Democrats Gleeful at Prospect of Running Against Gingrich.’ That’s the first bit of Gingrich-related news that’s made me nervous.
* Duke University trustee Bruce Karsh and his wife Martha have donated $50 million to Duke for a permanent endowment to support need-based financial aid for undergraduate students from the United States and other countries, President Richard H. Brodhead announced Monday.
* Henry Aaron: So… here is my prediction. The Supreme Court will sustain the individual mandate, and it will do so not by the narrow 5 to 4 split that has become so familiar, but by a vote of 7 to 2. Or 8 to 1. Justices Breyer, Ginsburg, Sottamayor, and Kagan are virtually certain to find the mandate constitutional. But also voting to sustain it, I believe, will be Justices Scalia and Kennedy, based on reasoning similar to that of Silberman and Sutton. Justices Roberts and Kennedy are in play and I am assuming that either or both will vote to affirm the mandate. Justice Thomas, who has staked out a far-reaching opposition to federal regulation in many currently accepted forms, will say that the mandate exceeds Congress’s constitutional authority.
* Apocalypse tomorrow: In fact, according to the latest science, says Anderson, “a 4 degrees C future is incompatible with an organized global community, is likely to be beyond ‘adaptation’, is devastating to the majority of ecosystems, and has a high probability of not being stable.”
* And today from America’s finest news source: Global Warming May Be Irreversible by 2006.
* But it’s okay that we’ve ruined this planet; after all, there’s always Keppler 22b.
* 10 Films You Should See at the Raindance Film Festival 2011. My cousin Chris’s brilliant Afghanistan documentary Where My Heart Beats clocks in at #9.
* And speaking of money: David Graeber vs. the Austrians.
* In these two books, we have two versions of school reform. One is devised by Wall Street financiers and politicians who believe in rigidly defined numerical goals and return on investment; they blame lazy teachers and self-interested unions when test scores are low. The other draws on the deep experience of a compassionate teacher who finds fault not with teachers, unions, or students, but with a society that refuses to take responsibility for the conditions in which its children live and learn—and who has demonstrated through her own efforts how one dedicated teacher has improved the education of poor young people.
* Bringing the number of planets discovered outside our solar system to 645, the 50-planet haul includes 16 super-Earths (planets with a mass between one and ten times that of Earth), including one that orbits at the edge of the habitable zone of its star). Sounds like it’s time to bring freedom to the HD85512bians.
* PKD Watch: The police department in Santa Cruz, California, has begun an experiment that uses a mathematical algorithm to predict when and where certain crimes will be committed, and puts police on the scene before they happen.
State law already bans same-sex marriage, and opponents of a constitutional amendment contend that it is unnecessary. North Carolina is the only state in the Southeast without such a provision in its constitution.
We cannot allow a discrimination gap. Rally in Raleigh this afternoon. Unfortunately I have a commitment on campus at noon or I’d go myself.
* First, the big news: Casey Affleck has admitted I’m Still Here is a hoax. Shock! Terror!
* Jon Stewart and Stephen Colbert will hold “competing” rallies on the Mall in Washington, D.C., to restore sanity and keep fear alive respectively. I think this is a good idea and I’m glad they’re doing it, but it’s frustrating to once again see legitimate criticism of Bush equated with totally insane criticism of Obama in the name of “balance” and “moderation.”
* Our long national nightmare is finally over: Karl Rove has surrendered to Christine O’Donnell.
* Understanding the Tea Party, from Glenn Greenwald. A good pullquote: Given all that, I’d really like to hear what it is about Christine O’Donnell, or Sharron Angle, or any of these other candidates that sets them apart from decades of radical right-wing elected officials who came before them? They seem far more similar to me than different. When was this idealized era of GOP Adult Reasonableness?
* The first Earth-like planet orbiting another star will be announced in May next year, if the discovery of extrasolar planets continues at its present rate, say researchers Samuel Arbesman from Harvard Medical School in Boston and Gregory Laughlin at the University of California, Santa Cruz.
Melissa Boteach, my colleague who focuses on poverty issues, points out that congress has the opportunity to act before things get even worse:
In just two weeks a job-creation engine known as the TANF Emergency Fund will expire, forcing states to begin shutting down successful partnerships with the private sector that have already created nearly a quarter-million jobs for low-income families. Congress must act before September 30 to extend the TANF Emergency Fund for another year and allow this innovative jobs program to continue.
Unfortunately, congress is typically more interested in the tax burden of millionaires than in the welfare of the poor and near-poor.
* Self-absorbed, self-indulged, and self-loathing, the Baby Boom generation at last has the chance to step out of the so-called Greatest Generation’s historical shadow. Boomers may not have the opportunity to save the world, as their predecessors did, but they can still redeem themselves by saving the American economy from the fiscal mess that they, and their fathers and mothers, are leaving behind.

* And All-Star Superman will be made into animated movie. I don’t know why it hasn’t been green-lit for the next live-action Superman yet. Jon Hamm could kill it.
A dream deep inside me, long thought dead, reawakens: Alpha Centauri may have an Earth-like planet in the habitable zone. Via Monkeyfilter.
