The disturbing Fermi Paradox suggests we should have made contact with an extraterrestrial civilisation by now, yet we haven't. By applying a 500-year-old philosophical principle, a Cornell University researcher has shown that the Great Silence is not unexpected — we just need to give it more time.

Tutankhamun, the boy king of ancient Egypt who died at 18 and later exploded inside his own sarcophagus, apparently owned — and was buried with — a literal space dagger made from meteoric iron.
In a few years, powerful new telescopes will usher in a search for habitable worlds outside our solar system. And TRAPPIST-1 — a dim, tepid star just a smidge larger than Jupiter — is one of the first places we'll look. It's only 40 light years away, and it's home to several promising, Earth-sized exoplanets.
Last year, the search for extraterrestrial intelligence got a major boost when Russian billionaire Yuri Milner unveiled a $US100 million effort to scan the skies for radio and light signals emitted by aliens. Not content to simply sit tight and wait for ET to hail us, Milner now plans to build interstellar spacecraft. Yes, you heard that correctly.
Should we ever detect an extraterrestrial civilisation, or any kind of alien life for that matter, it's a safe bet they will look very different from us. They will 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 will be like.
Gale Anne Hurd became famous for producing movies like The Terminator, Aliens, and Armageddon. But these days, she's better known as the producer of The Walking Dead and Fear the Walking Dead. Now, she's producing Hunters for Syfy, and she told us why it's her most political show yet.
For more than 50 years, astronomers have pointed radio receivers to the sky and listened for signs of intelligent life — mostly, around stars like our own. Since that doesn't seem to be working out so well, a team of SETI researchers is now proposing something radically different: scanning the oldest and dimmest stars in the galaxy.
Humans have long dreamed of discovering intelligent life beyond Earth. But truth is, we have no way of knowing if an alien civilisation would be friendly or hostile. Should we have the rotten luck of discovering the Borg, we'll need to get our collective asses into hiding quickly — and a team of astronomers thinks they know how we can. Naturally, it involves lasers.
