To Learn How Aliens Think, We Must First Learn About Their Biology

Should E.T. finally give Earth a ring, it's not only important to understand what the message says but why it is being sent, a speaker at a talk about extraterrestrials urged this week.

Titled Archaeology, Anthropology and Interstellar Communication and edited by SETI Director of Interstellar Message Composition Douglas Vakoch, the document draws on "issues at the core of contemporary archaeology and anthropology" to prepare us "for contact with an extraterrestrial civilization, should that day ever… »5/24/14 8:00pm5/24/14 8:00pm

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 2:14pm1/28/14 2:14pm

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 11:00am12/05/13 11:00am

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 11:30am9/08/13 11:30am

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 8:19pm4/22/13 8:19pm

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 5:39pm6/27/12 5:39pm

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

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 10:00am12/28/11 10:00am

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 5:30pm12/05/11 5:30pm
