A team of astronomers monitoring data from the Kepler, a craft designed to identify potenially habitable stars, have just announced today that they have located one orbiting a double star system (NYT Link). Early data suggests it's a gaseous planet, but it is also within the range considered "sustainable for life". Still, if there's no life there, Kepler's got over a thousand other exoplanets to check out. Officially, the newly-discovered planet is named "Kepler 16b," but astronomers have already nicknamed it "Tatooine".
Sure, the diamond planet is real....if you believe the liberal media. One of the scientists involved in making this discovery (actual abstract here) discusses how his experience would have been different if he was a climate scientist. [more inside]

ESO scientists have found an 'extremely primitive star' in the Milky Way's halo - 4/5 the size of the Sun, one of the oldest ever found - that theory says is impossible. It has fifty times less lithium in it than expected in the material produced by the Big Bang. [more inside]
Saturday August 27 Bill Nye dedicated a solar noon clock he designed. The clock is embedded in the facade of Rhodes Hall. At Solar Noon, when the Sun culminates, that is, reaches its highest point in the sky, the sun-shaped feature will light up. It is the marrying of mechanical and electrical engineering with astronomy. What could be better?
NASA's Juno spacecraft launched this morning and is en route to Jupiter (launch video). Equipped with microwave, ultraviolet, infrared, and visible light detectors Juno will investigate the origins, atmosphere, and magnetosphere of the Solar System's largest planets over one year beginning with its arrival in 2016. Using its awesome solar-powered technology Juno will show Jupiter's magnetic field in detail never before seen. We probably won't hear much from Juno again until 2013, when it makes a fly-by of Earth. You can follow Juno on Twitter, so if it types out its scream, someone will hear it. Also
screaming traveling aboard Juno are three very special LEGO mini-figurines.
Jupiter has lots. Mars has some, too, as does Neptune. Turns out Earth's got a trojan asteroid of its own. Meet 2010 TK7, the blue planet's new baby brother.

On July 5th the SOlar and Heliospheric Observatory (SOHO) captured video of a comet, known as a sungrazer, in route to collide with our star. SOHO is equipped with an occluding coronograph that blocks direct sunlight and reveals the corona, but also prevents direct study of the terminal impact of sungrazers. But on July 6th, with the help of the Solar Dynamics Observatory (SDO), astronomers were able to observe the comet (slyt) streaking in front of the surface of the sun for the first time in history. It likely disintegrated before impact due to extreme heat and radiation.
The House appropriations panel that oversees NASA has proposed a spending bill that would cut funding for the James Webb Space Telescope, the successor to the Hubble and the telescope many astronomers consider the best chance to continue and expand the Hubble's legacy. Here are the Subcommittee Members.

Sunspots, first observed by Galileo, normally follow an 11-year cycle. We are into a few years into (recorded) cycle number 24 but according to NASA it's looking rather underpowered. Nobody is certain exactly what the consequences will be, but one distinct possibility is a cold period; a previous low in solar activity, the Maunder minimum, is correlated with a brief Little Ice Age. Nobody really knows how this unusual solar weather pattern might interact with human-caused climate change. Previously, albeit somewhat controversially.

An 'armchair astronomer' named David Martines has found something on Google Mars which he believes is some kind of space station. Allegedly, NASA is investigating the image. Another theory says that what he sees is a "linear streak artifact produced by a cosmic ray".
French scientists have just published a paper entitled "Gliese 581d is the 1st discovered terrestrial-mass exoplanet in the habitable zone", claiming that their computer model suggests the exoplanet "will have a stable atmosphere and surface liquid water for a wide range of plausible cases." We've discovered a lot of exoplanets. And there are a lot of sites to help you keep track. Previously.

The discovery indicates there are many more free-floating Jupiter-mass planets that can't be seen. The team estimates there are about twice as many of them as stars. In addition, these worlds are thought to be at least as common as planets that orbit stars. This would add up to hundreds of billions of lone planets in our Milky Way galaxy alone.

Andreas Cellarius was a scholar of the 17th Century who produced one of the most famous cosmological atlases of all time, Harmonia Macrocosmica, featuring 29 beautiful plates (large, high-quality scans), illustrating various aspects of the Universe as understood by the Western science of his time. It's impossible to pick favorites among them, but here are three examples: Phases of the Moon, Sizes of the Celestial Bodies and Stars and Constellations of the Northern Sky.

Galileo Lectures In 2009, to mark the 400th anniversary of Galileo first turning a telescope skywards, Radio New Zealand National, in partnership with the Royal Society of New Zealand, released this kickin' series of five lectures spanning the evolution of cosmology, extra-solar planets, near-earth objects, the nascent field of neutrino astronomy and prospects for the future as the Square Kilometre Array radio telescope comes online early in the next decade. It's a great listen and best of all, it's free to download as MP3 or Ogg Vorbis!
A gamma ray burst nicknamed GRB 110328A (i.e. detected 3/28/2011) appears to be the legacy of a star being torn apart by a supermassive black hole, leaving a peak brightness one trillion times the sun's brightness as it met its ancient inevitable end.

Our solar system may have a ninth planet -- or a tenth, if you're a Pluto sentimentalist. Tyche, which astronomers suspect lurks in the Oort cloud, fifteen thousand times farther away from the sun than the Earth, is thought to be a gas giant four times the size of Jupiter. We may know for sure in April.
Several months ago, Bill Rankin of Radical Cartography (previously and previouslier) created an astronomical calendar of events for New Haven, Connecticut, where he lives, featuring all of the inexorable rhythms of the Solar System in one handy PNG file. Now you can create such a calendar for any location on the planet, with information as basic as the hours of daylight or as esoteric as the tilt of Saturn's rings, all lovingly rendered in soothing translucent pastels.

"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."

Yesterday there was a partial solar eclipse over most of Europe and northwestern Asia. There were a lot of great pictures, but the most spectacular may have been the solar transit of the International Space Station during the partial eclipse, taken by French astrophotographer, Thierry Legault. Bad Astronomy has more on why he chose the Sultanate of Oman, and how he captured a picture that was possible for less than a second. Bad Astronomy also covered his picture of the lunar transit of ISS, captured December 21, 2010.

A hot carbon-rich gas giant exoplanet, WASP-12b, has been discovered. As the lead author of the paper being published today, Nikku Madhusudhan, says: ""This planet reveals the astounding diversity of worlds out there". In particular, the discovery supports theories that there are likely to be planets made of diamond and graphite out there.
Amid news of new extrasolar planet discoveries, including a system with a possible 7 planets, Greg Laughlin and Sam Arbesman have released a paper that will be published next month in the open-access journal PLoS One. "A Scientometric Prediction of the Discovery of the First Potentially Habitable Planet with a Mass Similar to Earth" (pdf of full paper) boldly predicts that: "the first potentially habitable planet will be discovered, in this case, as early as May 2011, and likely by the end of 2013." NASA's Kepler mission is set to release data on hundreds of candidate planets early next year. The mission has discovered 7 so far. (Pre-vio-usly)
Emily Lakdawalla has published the first 42 of 99 Voyager Mission Status Bulletins (thanks to space fan Tom Faber). Before the days of the internet, updates on space missions were distributed via newsletter. From 1977-1990 NASA published these Voyager newsletters to update scientists and enthusiasts. Both Voyager I and Voyager II are still out there, hurtling toward the stars. Voyager I and II weekly status updates from 1995-present are currently available online. Lakdawalla will be publishing the rest of the bulletins after she indexes them.
