The world's largest optical SETI telescope begins sweeping millions of stars for laser signals from alien civilizations.
The Allen Telescope Array is swallowing terabytes of celestial radio data in the ongoing hunt for alien signals from space. The SETI Institute is about to hand out the data to anyone with ideas for new ways to sift it.
Astronomers have shut down the innovative Allen Telescope Array in northern California — a huge blow to the ongoing search for extraterrestrial intelligence.
It seems unlikely that life could arise on giant, gaseous exoplanets. But what about their moons?
Sky & Telescope interviews Seth Shostak, senior astronomer at the SETI Institute, on the hunt for extraterrestrial intelligence.
Searchers for extraterrestrial intelligence reach a humble conclusion: we don't know what we don't know.
Although funding has eroded for SETI@home and the Allen Telescope Array in the past few years, both alien-hunting projects have survived, thanks to donors and volunteers.
Several big hunts are seeking radio and laser emissions from other civilizations among the stars. From the Allen Telescope Array to SETI@home, here's a rundown of all recent and current searches.
Why the world's biggest search should reverse its strategy and why the first signal we hear will probably come from an extremely powerful civilization extremely far away.
SETI researchers have long had to beg time on instruments built for conventional radio astronomy. Now they've built one of their own.
Frank Drake's famous equation helps to quantify our chance of finding ETs or at least to pose the essential questions.
Searches for extraterrestrial intelligence are about to expand into new realms, thanks to new advances in technology and new thinking.
