The debate over possible evidence for life on Mars is one of the most hotly debated subjects in space science, and some news released Feb. 27 is sure to add fuel to the fire. Studies of a Martian meteorite, known [...]

Of Exoplanets and Habitability: Exploring the Possibility of 'Superhabitable Worlds'

Artist’s impression of an exoplanet with a mass approximately 3.6 times that of Earth, discovered orbiting just inside of the habitable zone of the Sun-like star HD 85512. Are “Super-Earths” such as this the most promising candidates for harboring extraterrestrial life? Image Credit: ESO/M. Kornmesser
