Saturn’s Moon Enceladus Has the Basic Ingredients For Life

Saturn’s moon Enceladus features a warm subterranean ocean covered in ice. In an extraordinary new finding, scientists have confirmed the existence of a chemical energy source within this moon’s water that’s capable of sustaining living organisms here on Earth. Enceladus is now officially the best place beyond Earth to look for life. Read More >>

Alien Life Could Be Island Hopping Between TRAPPIST-1 Planets

The TRAPPIST-1 system has totally entranced Earthlings since NASA announced its discovery last month. For both astronomers and tinfoil hat believers (*raises hand*), TRAPPIST-1 is a sign of hope for finding alien life, since three of its planets are located in the habitable zone which supports liquid water. With water comes life, and with life comes alien conspiracy theories—at least that’s the idea. Read More >>

NASA Didn’t Find Life on Mars—But It Did Find Something Very Cool

If we ever get proof of past life on Mars, it’ll come in the form of biosignatures, fingerprints that could only have been left by living organisms. We’re a long way from finding that smoking gun evidence, but an analysis of silica minerals discovered by NASA’s Spirit rover pushes us one step closer. Because of their similarity to silica deposits shaped by microbial life on Earth, these intriguing Martian minerals are now being called a “potential biosignature.” Read More >>

There’s Growing Evidence That Venus Was Once Habitable

If you could hop in a time-travelling spacecraft, go back three billion years and land any place in our solar system, where would you want to end up? Earth, with its barren continents and unbreathable atmosphere? Or Mars, a chillier version its big brother? Wait, what about Venus? Read More >>

The Prospects for Alien Life on Titan Keep Getting Better

Saturn’s moon Titan is a frigid hellscape by Earth standards, but it’s also one of the most hopeful spots for discovering alien life in our solar system. A new scientific paper hints that conditions on Titan’s surface might be favourable for the chemistry of life to emerge. Read More >>

The Surprisingly Obvious Way We Could Hunt for Alien Life

A team of astronomers is proposing a new way to hunt for intelligent life that sounds rather obvious when you think about it: we need to be the aliens. Or at least, we need to put ourselves in their shoes and think about where in the sky they can see us. Read More >>

New Scale Pinpoints Most Life-Friendly Alien Planets 

Researchers at the University of Washington’s Virtual Planetary Laboratory have devised a new habitability index for judging how suitable alien planets might be for life. The point of the exercise is to help scientists prioritise future targets for close-ups from NASA’s yet-to-be-launched James Webb Space Telescope and other instruments. Read More >>

What Sorts of Life Forms Could Actually Live on Mars?

NASA this week reignited our hopes of finding alien life when it announced the first direct evidence of liquid water on Mars. But before we start indulging in fantasies of space crabs and reptilian beings, we ought to remember that Mars is a frigid world with a thin atmosphere. And that raises an obvious question: what sorts of life forms could actually live there? Read More >>

“Curtain Eruptions” on Enceladus Give Us a New Look at Saturn’s Moon

Enceladus, Saturn’s sixth largest moon, is a cold ball encrusted almost entirely in ice. One of its defining features are geyser-like jets of water vapour that shoot out of its surface. But a new analysis suggests those jets are not jets after all, but something odder: curtain eruptions. Read More >>

SETI Man Thinks We’ll Find Aliens Within 20 Years

One of the key men behind the SETI project thinks that advances in processing power means we're likely to find concrete evidence of alien life within the next 20 years, which will certainly give the Pope something interesting to tweet about. Read More >>
