The iconic Hubble Space Telescope turns 25 this month, and getting the ball rolling on a life-hunting successor instrument would be a fitting birthday present, one prominent researcher argues.
Scientists have found complex organic molecules in a planet-forming disk of gas, dust and ice swirling around a very young star, evidence that the building blocks for life may be common in the universe.
Humanity is on the verge of discovering alien life, high-ranking NASA scientists say.
Astronomers have devised an instrument that could lift the veil of doubt over whether we're alone in the universe.
A study based on 151 multi-planetary systems found by NASA's Kepler space telescope shows that most have a planet -- or two or three.
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.
Hints that Jupiter's moon Ganymede, the largest moon in the solar system, has a subsurface ocean date back more than 40 years, but it took the Hubble Space Telescope and some clever scientific detective work by to come up with the proof.
Cute, squishy face, bug eyes, and a penchant for peanut M&Ms? Increasing amounts of research suggest the alien life we've been searching for won't look like anything Hollywood has yet imagined. And it might exist without compounds we deem essential.
