A New Scientific Model that Defines Alien Intelligence

Should we ever detect an extraterrestrial civilization, or any kind of alien life for that matter, it's a safe bet they'll look very different from us. They'll also probably think in a way that's completely foreign to what we're used to. Here's how experts believe we might be able to predict what the minds of aliens… » 1/28/14 11:14am 1/28/14 11:14am

Congress Just Held a Remarkable Two-Hour Hearing on Aliens

In a refreshingly pro-science move, the House Science Committee set aside two hours yesterday to discuss the ongoing search for extraterrestrial life. The ensuing conversation was fascinating, but at times infuriating, with the experts discussing everything from alien biosignatures to the possibility that we're being… » 12/05/13 8:00am 12/05/13 8:00am

Could we detect signs of alien life on a dying planet?

Scientists say that we should be on the lookout for purple planets, a possible sign of primordial extraterrestrial life. But what about the biosignatures of exoplanets that are dying? A recent study concluded that it is indeed possible — we just have to recognize the signs. » 11/25/13 1:20pm 11/25/13 1:20pm

Some of the Most Plausible Scenarios for Alien Civilizations

We have yet to make contact with an extraterrestrial intelligence, making it exceedingly difficult for us to imagine what an alien civilization might be like. But that doesn’t mean we can’t make some educated guesses. Here’s what we know — and don’t know — about aliens. » 11/04/13 11:00am 11/04/13 11:00am

How we could start looking for alien transmitters in our solar system

SETI now has the technology to go snooping for extraterrestrials in our own backyard. No, not as close as little green men cutting up crop circles. Rather, we should be able to detect an alien device positioned somewhere between the sun to 30 times farther out than Pluto. » 10/17/13 1:30pm 10/17/13 1:30pm

When did we start believing in Martians? Why did we stop?

Today, we have rovers busily studying the surface of Mars, but 100 years ago, it wasn't uncommon for people to believe that intelligent Martians occupied the Red Planet, and 100 years before that, visions of Moon dwellers danced in many people's heads. Where did these ideas of nearby intelligent extraterrestrials come… » 9/08/13 8:30am 9/08/13 8:30am

These weird stories prove that extraterrestrials love Russia

Anthropologists explain how to approach aliens parked in Earth orbit

It happens all the time in science fiction stories: aliens park their vessels in Earth orbit, and things go pear-shaped. But what if this scenario unfolded in real life? What would be the best thing for us to do? We asked several anthropologists the best way to go about communicating with truly unknown life forms. » 4/22/13 5:19pm 4/22/13 5:19pm

How to Measure the Power of Alien Civilizations Using the Kardashev…

We have yet to make contact with an extraterrestrial civilization. If they're out there — and surely they must be — we haven't the foggiest idea what they might be like. Or do we? » 2/25/13 11:00am 2/25/13 11:00am

How science fictional will AMC's 1950s drama Area 51 be?

Is SETI at risk of downloading a malicious virus from outer space?

We take it for granted that the search for extraterrestrial intelligence (SETI) is a safe endeavor. Seriously, what could possibly go wrong with passively searching for interstellar radio signals? Unfortunately, the answer is quite a lot –- especially if the incoming signal contains something malicious, like a… » 6/27/12 2:39pm 6/27/12 2:39pm

Meet SETI's new boss: Geoff Marcy, the planet hunter

Geoff Marcy has spent the better part of his career peering into the depths of space in the search for exoplanets and brown dwarfs. His pioneering work has resulted in the discovery of over 110 planets outside of our own solar system - including the first system of planets orbiting a distant star. But now, Marcy has… » 6/08/12 7:10am 6/08/12 7:10am

Evidence of extraterrestrial life could be sitting on the Moon at this …

When you consider the utter vastness of space, it isn't hard to accept that, somewhere out there, extraterrestrial life probably exists. That being said, one can just as soon reason that the Universe is so immense, the odds of us actually finding evidence for the existence of alien organisms are probably pretty slim.… » 12/28/11 7:00am 12/28/11 7:00am

Why Silicon-based Aliens Would Rather Eat Our Cities Than Us

What would non-carbon-based life really be like? What would it want from us? Bruce Dorminey, science journalist and author of "Distant Wanderers: The Search for Planets Beyond the Solar System," interviews NASA astrochemist Max Bernstein about the possibility of silicon-based life, in an article from Universe Today. » 12/05/11 2:30pm 12/05/11 2:30pm
