Jul 21st, 2008 · A team of astronomers announced they have discovered the smallest and potentially most Earth-like extrasolar planet yet. Five times as massive as Earth, it orbits a relatively cool star at a distance that would provide earthly temperatures as well, signaling …
Jul 18th, 2008 · NASA's Deep Impact spacecraft (whose extended mission is called EPOXI) has created a video of the moon transiting Earth as seen from 31 million miles away. Scientists are using the video to develop techniques to study alien worlds. 'Our video shows some …
Mar 20th, 2008 · NASA scientists have discovered the first evidence of organic molecules on an extrasolar planet. Using the Hubble Space Telescope, they detected trace amounts of methane on a swirling gas giant about 63 light-years from our own planet. Being a gas giant, …
Aug 5th, 2007 · Sentient Developments revisits the Fermi Paradox which is "the contradictory and counter-intuitive observation that we have yet to see any evidence for the existence of Extra Terrestrial Intelligence (ETI) although the size and age of the Universe suggests …
Jun 11th, 2007 · You might recall not too long ago the first photo of an extra solar planet or, more recently, the mapping & speculation on these planets that lie outside our own solar system. Long since those first few spotted in the 90s, we're now starting to find …
May 18th, 2007 · BlueMorpho writes with a link to a Space.com article about a recently discovered extrasolar planet that may be able to harbor 'life as we know it.' Orbiting around the star Gliese 581 is a small rocky ball that might have the same liquid ocean and drifting …
May 13th, 2007 · Data from the Spitzer Space Telescope has been used by researchers to make the first-ever map of an extrasolar planet. It's a weather map, more precisely, showing temperature variations over the surface of a Hot Jupiter. It really is hot: even the coldest …
Apr 10th, 2007 · Astronomers have long suspected that water should exist in the atmospheres of extrasolar planets. Now they have evidence. Water has been discovered in a planet called HD209458b, which was previously found to have oxygen. From the article: 'The discovery …
Oct 12th, 2006 · Physorg is running an interesting article on the most recent of Hubble's accomplishments. It has provided us evidence supporting that which Emmanuel Kant proposed over 200 years ago — that planets do indeed form from disks of gas and dust that surround …
Dec 5th, 2005 · Science Daily is reporting on a new device called an Optical Vortex Coronagraph that's been invented to directly image planets orbiting other stars by using a special lens that "spins out" the light from the star leaving only the reflected light …
Jul 14th, 2005 · CNN is reporting that a planet has been discovered in a solar system with 3 suns. The observation brings into doubt the theory stating that planets form from the dust orbiting around a single sun. The discovery also resulted in a new method of searching …
Jun 13th, 2005 · Astronomers have discovered a rocky, terrestrial planet orbiting a nearby star, Gliese 876. The planet has approximately 7.5 times the mass of the Earth, double its radius, and orbits its parent star once every two days. This is the most Earthlike extrasolar …
Apr 30th, 2005 · The year-long controversy about whether the European Southern Observatory had indeed captured the first picture of an extrasolar planet has apparently been resolved. Journal publication today of a fuzzy image of this Jupiter-sized, extrasolar planet led …
