A pioneering infrared scan of 100,000 galaxies by Penn State astronomers has failed to detect any signs of galaxy-spanning extraterrestrial supercivilizations. This result, though very preliminary, may be a sign that aliens aren't capable of conquering entire galaxies. »
Four hundred and fifty five light years away sits a newborn star that bears striking resemblance to our Sun. It’s awash in a sea of complex organic molecules which could, one day, coalesce to form proteins, nucleic acids, even life itself.
Volcanoes are often painted as harbingers of destruction—and for good reason. But sometimes, they can help life survive, by feeding energy-starved ecosystems elemental carbon. »
By studying the subtle shifts of aurorae on Ganymede, scientists working with the Hubble Space Telescope have concluded that Jupiter's largest moon hosts a massive subterranean ocean. Quite suddenly, the outer reaches of our solar system appear to be a very wet place, indeed. »
Move over Europa, there's another moon out to claim the title of first place we'll discover extraterrestrial life. New research from Cornell University finds that alien microbes could, just maybe, eek it out on Saturn's largest moon, Titan. But these critters wouldn't be like anything we've ever seen before—not even… »
You must watch the entire US Congress' hearing on the search for alien life—it has so many awesome moments. It fills me with hope that at last some people in Washington are truly interested in the greatest discovery that Humanity would ever make. »
In the early days of space exploration, NASA basically made up procedure on the fly. With little knowledge of the world outside our atmosphere, agency physicians worried what humans might encounter out there. Maybe John Glenn would go Space Blind. Maybe the Apollo 11 crew would track an Andromeda Strain through the… »
The idea of life on Mars never gets old, but while we know it would never involve little green men, we've never really known what we might find. When a Mars training mission recently unearthed a thriving world of microbes below the Atacama desert in Chile, however, we got a much better idea. »
