I've always wanted to have a neighbor just like you

Won't you please, please won't you be my neighbor? NASA's Kepler Discovers First Earth-Size Planet In The 'Habitable Zone' of Another Star. Kepler-186f is a planet about ten percent bigger than Earth that orbits within the habitable zone of its star. The light there is dim and orange, and it only gets about a third of the sunshine we do, but that may be enough for life. If you go outside tonight, there might be someone 500 light years away looking back at you...

Make your own solar system

The Kepler mission has changed the way we think about extrasolar planets and their abundance. It turns out that nature produces a bewildering variety of planetary systems, each in their own infinite majesty. But maybe, just maybe, you can do better? [more inside]

One procedural universe, coming right up

Space Engine is a free (but not open source) program that allows you to fly through vast reaches of the universe. Along the way, you'll see some pretty amazing vistas and probably want to take screenshots of them. It incorporates a good amount of real-world data about the solar system, exoplanets and the universe in general with procedural generation of everything we don't know. [more inside]

Exoplanet Hunter

"It was one of those things that was a gift to humanity... We’re all going to lose for sure." Kepler's career is over, but not before answering one of mankind's most profound questions.

Ad Astra Incrementis

Carl Sagan wrote, “We began as wanderers, and we are wanderers still. We have lingered long enough on the shores of the cosmic ocean. We are ready at last to set sail for the stars.” But how will humans or our machine representatives fly to the stars? [more inside]

1,000 new worlds

NASA has announced that the latest Kepler data dump contains 1,091 extrasolar planet candidates, with 196 Earth-sized planets among them. The data shows "a clear trend toward smaller planets at longer orbital periods is evident with each new catalog release. This suggests that Earth-size planets in the habitable zone are forthcoming if, indeed, such planets are abundant." Total Kepler candidates as of February 27, 2012: 2,321. [more inside]

The tiniest star system

Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.

Other earths, circling different suns

The Habitable Exoplanets Catalog is a database of the planets outside our solar system which are considered the most suitable for life according to certain steps and metrics. So far 16 have been identified as possible candidates. This Guardian article is a good introduction. You can also just dive into the catalogue, which ranks planets on two main scales, similarity to Earth and surface habitability (note that all images are computer renderings). The catalog is a project of the Planetary Habitability Laboratory at University of Puerto Rico in Arecibo (home to the world's largest radiotelescope).

French scientists reportable habitable planet orbiting another star

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.

Planets made of diamond and graphite?

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.

"A novel metric of habitability"

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 fi rst 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)

You're not alone

Many planets have been found circling other stars, but the prevailing search techniques turn up results encouraging but bizarre. (encouraging, previously) Gravitational micro-lensing has made it possible to OGLE a solar system much like our own.... You're not alone.

A home away from home?

Spacefilter: ESA telescope detects planet 20 lightyears away with a temperature between 0 and 40 degrees Celsius, dubbed "most Earth-like planet yet."
