While exoplanets are now being discovered by the thousands, it is still a painstaking process to determine any specific details about them, since they are so incredibly far away. However, astronomers have been devising new techniques to do just that, including […]

Hot 'Super-Earths' Provide Clues to Water in Exoplanet Atmospheres
