Hubble Telescope reveals variation between hot extrasolar planet atmospheres
Jul 08, 2013 (SPX)
First results from the analysis of eight 'hot Jupiter' exoplanets suggest that winds and clouds play an important role in the atmospheric make up of these exoti...
UCSB Astronomer Uncovers The Hidden Identity Of An Exoplanet
Jul 04, 2013 (SPX)
Hovering about 70 light-years from Earth -- that's "next door" by astronomical standards -- is a star astronomers call HD 97658, which is almost bright enough t...

1 star, 3 habitable planets
Jun 28, 2013 (SPX)
A team of astronomers, including Carnegie's Paul Butler, has combined new observations with existing data to reveal a solar system packed full of planets. The s...
Three planets in habitable zone of nearby star
Jun 27, 2013 (SPX)
Gliese 667C is a very well-studied star. Just over one third of the mass of the Sun, it is part of a triple star system known as Gliese 667 (also referred to as...
Gas-giant exoplanets seen clinging close to their parent stars
Jun 27, 2013 (UPI)

First Transiting Planets in a Star Cluster Discovered
Jun 27, 2013 (SPX)
All stars begin their lives in groups. Most stars, including our Sun, are born in small, benign groups that quickly fall apart. Others form in huge, dense swarm...
Study finds planets in habitable zone around a distant star
Jun 25, 2013 (UPI)
