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.

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.

Alien life may well have flourished many times around our galaxy, and even our solar system. Why haven't we found it, though? It probably lived and died long before we were around, and didn't last long enough to evolve into complex multicellular forms. A new study published by scientists and researchers at the Australian National University suggests that near-universal early extinction of other lifeforms in our universe — at a cellular and microbial level — is due to the relatively rapid change of the climates on planets like Venus and Mars.

In 1977, astronomer Jerry R. Ehman observed a data signal so unique he drew a red circle around it and wrote "Wow!" to emphasise the discovery. The source of the signal was never identified, leading some to say it was aliens. But a new study suggests it wasn't aliens at all — but rather a hydrogen cloud caused by comets.
