Missing planets attest to destructive power of stars' tides

— 28 Apr 2009 10:49 | Astronomy

During the last two decades, astronomers have found hundreds of planets orbiting stars outside our solar system. New research indicates they might have found even more except for one... — full story

This artist's conception shows a hypothetical twin Earth orbiting a Sun-like star. A new study shows that characterising a distant Earth's atmosphere will be difficult, even using next-generation technology like the James Webb Space Telescope. If an Earth-like world is nearby, though, then by adding observations of a number of transits, astronomers should be able to detect biomarkers like methane or ozone, (c) David A. Aguilar (CfA)Finding twin Earths: Harder than we thought!

Does a twin Earth exist somewhere in our galaxy? Astronomers are getting closer and closer to finding an Earth-sized planet in an Earth-like orbit. NASA's Kepler spacecraft just launched... — full story

This artist's conception reveals the newly discovered Super-Neptune planet orbiting a star 120 light years away from Earth. Normally blue in colour, its red hue is caused by the illumination from the nearby Red Dwarf star, (c) David A. Aguilar (CfA)Astronomers discover extrasolar Super-Neptune

Astronomers at the Harvard-Smithsonian Centre for Astrophysics have discovered a planet somewhat larger and more massive than Neptune orbiting a star 120 light-years from Earth. While... — full story

Artist's impression of the planet OGLE-TR-L9b. Circling its host star in about 2.5 days, it lies at only three percent of the Earth-Sun distance from its star, making the planet very hot with a bloated roiling atmosphere. The star itself is the hottest star with a planet ever discovered, (c) ESO, H. ZodetThree students discover unique planet

Artist's impression of the extrasolar planet HD 189733b, now known to have methane and water. Astronomers used the Hubble Space Telescope to detect methane - the first organic molecule found on an extrasolar planet. Hubble also confirmed the presence of water vapour in the Jupiter-size planet's atmosphere, a discovery made in 2007 with the help of the Spitzer Space Telescope. They made the finding by studying how light from the host star filters through the planet's atmosphere, (c) ESA, NASA and G. Tinetti (University College London, UK and ESA)First organic molecule on extrasolar planet discovered with Hubble
