A recent study from NASA's Goddard Institute for Space Studies (GISS) has produced a new 3-D model for determining exoplanet habitability. The post Looking for Signs of Life on Distant Planets Just Got Easier appeared fi...

A spacewalking astronaut successfully replaced a blurry camera outside the International Space Station on Friday, but had to contend with a balky jetpack and a frayed safety tether.

"The search for planets is the search for life," said Natalie Batalha, a Kepler mission scientist from NASA's Ames Research Center. "These results will form the basis for future searches for life." "Forty years ago, peop...

A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe.

"We're not saying nothing happened," said co-author Dr William Foster, a palaeontologist from the Jackson School of Geosciences at the University of Texas at Austin. "Rather, global oceans in the extinction's aftermath w...
