Playing hide and seek with exoplanets
U. COLORADO (US)—A precise “laser ruler” is being developed to look for Earth-like planets around other stars. The device will measure tiny changes in infrared light caused by the gravitational wobble of small, cool stars as they are tugged back and forth by their rocky planets. (more…)

Model suggests it’s raining rocks on exoplanet
WASHINGTON-ST. LOUIS (US)—An exoplanet discovered last February by the COROT space telescope is close enough to its star that its “day-face” is hot enough to melt rock. Theoretical models suggest the planet has a gaseous-rock atmosphere and boiling oceans on its surface. (more…)
