A new $100 million initiative invites the world's top minds to scour the universe for signals from distant planets. Continue reading →
On Monday, famed theoretical physicist Stephen Hawking announced the launch of a new $100 million effort to track down an alien civilization within the next decade.
A wide-ranging search of faraway galaxies has turned up no obvious signs of advanced alien civilizations.
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.
Astronomers have devised an instrument that could lift the veil of doubt over whether we're alone in the universe.
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.
Does it exist or not? Astronomers are claiming that the potentially habitable exoplanet is just noisy data, while others say it's too early to discount the existence of Gliese 581d.
The hunt for signs of life on planets beyond our solar system should cast as wide a net as possible, some researchers stress.
