Water and carbon monoxide have been detected in the atmosphere of a super-sized exoplanet 129 light years away.
Europe today inked a partnership deal with Russia for its two spacecraft ExoMars mission, planned to launch in 2016 and 2018.
Russia essentially replaces the United States, which backed out of the deal last year when the Obama administration eliminated the funding for most of NASA’s planetary program.
Astronomers today celebrate the official turning-on of ALMA, the world’s largest telescope.
ALMA is an array of 66 dishes tuned to wavelengths in the millimeter to submillimeter range of the electromagnetic spectrum, between the infrared and radio frequencies.
Computer simulations suggest that Pluto might have as many as ten undiscovered additional moons.
The planet already has five, so if this is true space is really crowded there, which might pose a problem for the New Horizons spacecraft that plans to fly past in 2015.
My heart bleeds: Congressman Steny Hoyer (D-Maryland) told employees at the Goddard Space Flight Center yesterday that sequester might force some layoffs there.
So, who does Hoyer work for, the employees at Goddard or the taxpayer? He apparently thinks he is the union rep for government employees.
Curiosity’s first drilling sample has found that the ancient watery conditions in Gale Crater were especially suitable for life.
Two stories today highlight not only the budget problems at NASA, but also illustrate the apparent unwillingness of both Congress and Americans to face the terrible budget difficulties of the federal government. In both cases, the focus is instead on trying to fund NASA at levels comparable to 2012, before the Obama administration or sequestration had imposed any budget cuts on the agency.
It is as if we live in a fantasy world, where a $16 trillion dollar debt does not exist, and where money grows on trees and we can spend as much as we want on anything we want.

Astronomers discover a trinary — of quasars.
Data from WISE has uncovered a binary brown dwarf star system only 6.5 light years away, the closest found in almost a century and the third closest overall.
Chicken Little Report: Four asteroids buzzed the Earth this past week.
I suspect that the increase in detected asteroids is not because there are more of them but because our ability to detect them continues to improve.

The uncertainty of science: New computer models find that the tropical rain forests will not be harmed by increased carbon dioxide in the atmosphere.
Tropical forests are unlikely to die off as a result of the predicted rise in atmospheric greenhouse gases this century, a new study finds. The analysis refutes previous work that predicted the catastrophic loss of the Amazon rainforest as one of the more startling potential outcomes of climate change.
In the most extensive study of its kind, an international team of scientists simulated the effect of business-as-usual emissions on the amounts of carbon locked up in tropical forests across Amazonia, Central America, Asia and Africa through to 2100. They compared the results from 22 different global climate models teamed with various models of land-surface processes. In all but one simulation, rainforests across the three regions retained their carbon stocks even as atmospheric carbon dioxide concentration increased throughout the century.
The study provides “robust evidence for the resilience of tropical rainforests”, says lead author Chris Huntingford, a climate modeller at the UK’s Centre for Ecology and Hydrology in Wallingford. But uncertainties remain, he adds.
First, this prediction is based on a computer model, which is as likely to be as right as the previous pessimistic predictions. With that in mind, no one should start dancing for joy. The long term consequences of increased carbon dioxide in the atmosphere remain unknown.
Second, I am baffled by the previous predictions that favored catastrophe for the tropical jungles because of increased levels of carbon dioxide. Plants breath CO2. They prosper from it. If you put more in the atmosphere they will thrive. Moreover, the tropical jungles are already hot, and the plant life there is adapted to that heat. Raising the global temperature should not hurt them significantly.
Finally, faced with a result that defuses all the crisis-mongering of the global warming crowd, the author of the article feels obliged at the end to emphasis their new bugaboo: extreme weather! It’s coming! Duck your heads!
But don’t worry. When weather extremes also fail to appear, they will find something else to scream about.
The uncertainty of science: The Russians now say that they have not found any previously unknown life forms in the sample from Lake Vostok.
Sergei Bulat of the genetics laboratory at the Saint Petersburg Institute of Nuclear Physics had said Thursday that samples obtained from the underground Lake Vostok in May 2012 contained a bacteria bearing no resemblance to existing types. But the head of the genetics laboratory at the same institute said on Saturday that the strange life forms were in fact nothing but contaminants.
It appears that the earlier announcement was either premature, or inappropriate.

The Russians have announced that their samples from Lake Vostok, buried deep under the Antarctic icecap, contains life, one of which is never before seen.
A sunstone, used by mariners to judge the position of the Sun when it is cloudy, has been found at a 16th century shipwreck.
A previous study showed that calcite crystals reveal the patterns of polarized light around the sun and, therefore, could have been used to determine its position in the sky even on cloudy days. That led researchers to believe these crystals, which are commonly found in Iceland and other parts of Scandinavia, might have been the powerful “sunstones” referred to in Norse legends, but they had no archaeological evidence to support their hypothesis—until now.

It is that time again! Today, March 4, NOAA released its monthly update of the Sun’s sunspot cycle, covering the period of February 2013. As I do every month, I am posting this latest graph, with annotations to give it context, below the fold.
Once again, the Sun has shown a complete inability to produce sunspots, at the very moment it had been predicted to be rising towards its maximum in the sunspot cycle. The numbers in February plunged from the tepid rise we saw in January to below the crash we saw in December. Right now, when the Sun is supposed to peaking, it is instead producing sunspots in numbers as low as seen in 2011, at the very end of the last solar minimum.

The day of reckoning looms: The true national debt.
Depending on what you include, the number could be as high as $31 trillion, twice what is normally mentioned. Worse, I’ve read other reports that suggest that even this number is low.
