New Scale Pinpoints Most Life-Friendly Alien Planets 


Researchers at the University of Washington’s Virtual Planetary Laboratory have devised a new habitability index for judging how suitable alien planets might be for life. The point of the exercise is to help scientists prioritize future targets for close-ups from NASA’s yet-to-be-launched James Webb Space Telescope »10/06/15 6:15pm10/06/15 6:15pm


Here's More Evidence That Galactic Super-Civilizations Don't Exist

Bill Nye Explains Why The Search For Alien Life Could End On Europa

Science guy Bill Nye says the two logical places to search for alien life in our solar system are Mars and Europa, the smallest of Jupiter's four moons. Why Europa? Nye gets into some details in this interview with Big Think, but here's the gist: Water. Water water. Water, water water water water; water water water! »7/31/14 6:00pm7/31/14 6:00pm
