What has Antarctica and Mars got in common? Mineral deposits from a briny subsurface aquifer suggest bacteria are hiding under the barren Antarctic landscape -- can the same be said for the red planet?
By studying ancient molecular clouds in our galaxy, astronomers have revealed that the universe's reservoir of water likely appeared much earlier than thought -- only a billion years after the Big Bang.
Saturn's icy moon Enceladus is showing definite signs of hydrothermal activity -- similar activity that is found along deep sea vents on Earth where water is heated and minerals are formed.
As NASA applauds its boosted budget request, scientists at NASA's Jet Propulsion Laboratory are excited to see a robotic mission to Europa take a big step towards being launched in the mid-2020s.
One of the least likely places you might think astronomers would learn about ancient supernovae is at the bottom of the ocean but scientists have done just that -- also dredging up a mystery. Continue reading →
Eight new exoplanets have been discovered, two of which are nearly Earth-sized orbiting within their stars' habitable zones. Continue reading
NASA’s Mars rover Curiosity’s discovery of organic compounds in the ground and plumes of methane in the air opens two potentially related investigations into whether or not the planet most like Earth in the solar system also hosted life.
A gas strongly associated with life on Earth has been detected again in the Martian atmosphere, opening a new chapter in a decade-old mystery about the on-again, off-again appearance of methane on Mars.
