The Land of Chocolate? Astronomers find sugar molecules orbiting young star IRAS 16293-2422, 400 light years away. “‘A big question is: how complex can these molecules become before they are incorporated into new planets?’ Jørgensen said. “This could tell us something about how life might arise elsewhere, and ALMA observations are going to be vital to unravel this mystery.'”

Going Up, Sir?
In the wake of Neil Armstrong’s passing, The New Statesman‘s Alex Hern makes the case for moving in the direction of a space elevator. The political argument aside, serious forays into space are clearly hindered by the prohibitive costs of leaving orbit more than anything else. If we are going to get serious about this, a space elevator is a technology that’s worth looking into. Right now, only Japan is on the case.
We have met the aliens…
By way of Eric of Kestrel’s Nest, our radio telescopes find signs of life on Mars…us. Hey, at least the system works. Although, does anyone else have a problem with UNC-Chapel Hill calling their robotic telescope network SKYNET? Inviting calamity, I say.
The Eagle has Landed.
Commander Neil Armstrong, the pioneer who took the first step on extra-terrestrial soil and towards our ultimate destiny, 1930-2012. “The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet…our opportunities are unlimited.“
The Secret Life of Hubble.
Until now. NASA uses crowdsourcing to unveil “Hubble’s hidden treasures”. The impressive pic above is “NGC 1763, part of the N11 star-forming region in the Large Magellanic Cloud,” submitted by one Josh Lake.
Earth, you are On Notice.
“Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us. And early in the twenty-first century came the great disillusionment.“
And we know exactly whose fault it is. In response to the 35-year-old “WOW signal“, we the people of Earth have apparently chosen as our herald Stephen Colbert, whose response above will be broadcast in the direction of its origin by National Geographic via the Arecibo radio telescope.
Hrm….isn’t the Mighty Colbert a bit too droll for alien intelligences? I fear this will set off a Douglas Adams-style miscommunication that will end very badly for all parties involved. Second, why would any alien race be able to make sense of Prometheus? There was no sense there to be had.

“These findings provide new insight into how the most massive galaxies in the Universe may have acquired their stars,’ said Michael McDonald, a scientist with the Massachusetts Institute of Technology (MIT), who led the study…’Our current understanding is that these massive galaxies assemble via mergers with smaller galaxies, but in this one cluster it looks like cooling-induced starbursts may be an equally important process.’“
Take that, Ed McMahon and Simon Cowell: Astronomers identify a galaxy cluster that is spewing out 3820 new stars a year, the fastest rate in the known universe. “Comparatively, the Milky Way forms stars at an average rate of just one solar mass (one star equal in mass to Earth’s Sun) per year. Other galaxies form an average of one star every 20 years.“
“The results were a big surprise. ‘We were shocked,’ says Kuhn. The sun doesn’t bulge much at all. It is 1.4m kilometres across, but the difference between its diameter at the equator and between the poles is only 10 kilometres.” Meanwhile closer to home, after fifty years of effort, astronomers conclude that our sun is the “most perfectly round natural object known in the universe.…Scaled to the size of a beachball, that difference is less than the width of a human hair.“
Crimson Twilight.
“Darkness crept back into the deserts of the red expanse. Rumors grew of a shadow in the East, whispers of a nameless fear.” Those two crazy Brits just landed, and already they’re paying dividends: Curiosity sends back this haunting vision of a Martian sunset. Update: Oops, sorry, this isn’t from Curiosity. It’s from the Mars Rovers, circa January 2009.
Distant Mirrors, and a Devouring Hunger.
“‘This is a major milestone on the road to finding Earth’s twin,’ said Douglas Hudgins, a scientist with the Kepler program…Kepler-22b, located about 600 light years away, has a radius 2.4 times bigger than the Earth, making it the smallest planet ever found in the middle of the habitable zone around a star.” Among the several fascinating announcements in astronomy in recent weeks (including Hubble passing the 10,000th mission mark), scientists announce the discovery of a faraway habitable planet, Kepler-22b. “Scientists don’t yet know whether it is a rocky, gaseous or liquid-covered planet.” But, don’t worry — the Air Force has top men looking into the situation. Top…men.
Moreover, just today scientists announced the discovery of two Earth-sized planets — Kepler 20e and Kepler 20f. “‘For the first time, we’ve crossed the threshold of finding Earth-size worlds,’ Torres says. ‘The next step is having an Earth-size planet in the habitable zone.’” And apparently Kepler 20f may have once had water, not unlike a planet closer to home…
“This is the single most bullet-proof observation that I can think of that we’ve made this entire mission regarding the liquid water.” Something to consider if we don’t manage to tackle global warming by 2006 — the prior existence of water on Mars is further confirmed through a trail of gypsum left within an ancient rock. “Both the chemistry and the structure ‘just scream water,’ Squyres added.“
And, on a grander scale, astronomers have begun to uncover supermassive black holes (no, not those ones) at the centers of galaxies. These are “the biggest, baddest black holes yet found in the universe, abyssal yawns 10 times the size of our solar system into which billions of Suns have vanished like a guilty thought.” In other words, plenty of room for Maximillian Schell to get lost in there…Tread carefully.
O Guo It’s Full of Stars.
“A dazzling green aurora frames the arc of the Milky Way over Jokulsarlon, the largest glacier lake in Iceland, in a picture taken in March. The image was a first-prize winner in the Second International Earth and Sky Photo Contest’s ‘Beauty of the Night Sky’ category.” Speaking of green lights, National Geographic chooses the top space photos of 2011.
