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

Kepler Recovery Efforts Conclude, Other Missions Mulled

Image Credit: NASA

After several months’ worth of review and testing, the team operating the Kepler Space Telescope has opted to close its efforts to make Kepler fully operational again. This follows the loss of one of the crucial components that controls the alien planet-hunting spacecraft. In an Aug. 15 teleconference, Charles Sobeck, deputy [...]
