Why a Mission to a Visiting Interstellar Object Could Be Our Best Bet for Finding Aliens

Life may exist elsewhere in the Milky Way galaxy, though try as they might, scientists have yet to detect any sign of it. Part of the problem has to do with the size of space; finding traces of organic substances or the waste signatures of alien megastructures isn’t easy at such cosmic distances. Fortunately, there’s the possibility that alien life will come to us in the form of interstellar objects. Read More >>

Why This Star-Packed Region of Space Is Likely Devoid of Life

Globular clusters are among the most fascinating celestial phenomena in the galaxy, packing a hideous amount of stars into a relatively tiny region of space. Given the sheer number and variety of stars within these clusters, it seems reasonable to think they’d also be packed with life. But as new research suggests, globular clusters are likely cosmic-scale wastelands. Read More >>

This Solar System Catalogue Could Be Key to Finding an Earth-Like Exoplanet

By searching for the telltale, periodic dimming of light from distant stars, astronomers can spot orbiting exoplanets tens to hundreds of light-years away. But how do they know what these bodies look like? Perhaps they first try to imagine how the planets in our own Solar System might appear to a faraway alien world. Read More >>

The Discovery of Complex Organic Molecules on Saturn’s Moon Enceladus Is a Huge Deal

Using data collected by NASA’s late-great Cassini space probe, scientists have detected traces of complex organic molecules seeping out from Enceladus’ ice-covered ocean. It’s yet another sign that this intriguing Saturnian moon has what it takes to sustain life. Read More >>

A New NASA-Led Project Means the Search for Aliens Is Heating Up

To date, scientists have catalogued more than 3,500 exoplanets, some of which may even be capable of fostering life. But we simply don’t know. The ability to detect life on distant worlds still eludes us, but a new project coordinated by NASA now takes us a significant step closer to achieving that goal. Read More >>

Our Galaxy Might Be Teeming With Habitable Exomoons

There are eight planets in our Solar System (sorry Pluto), but collectively, these planets host over 175 moons, one or two of which may even harbour life. Indeed, our galaxy, based on what we observe here, could be bursting with exomoons, a significant number of which may be capable of fostering life, according to new a new study. Read More >>

Intense Gravity of Super-Earths Could Trap Aliens on Their Home Planet

Rocky worlds larger than Earth are commonplace in the galaxy, and a few of them may even be habitable. Which poses an interesting question: How difficult would it be for aliens living on these super-Earths to launch rockets into space, given the tremendous gravity? According to new research, it would be difficult to the point of impossibility—meaning that some aliens may be perpetually trapped on their home worlds. Read More >>

Canadian Scientists Discover Freakishly Salty Lakes Hidden Under Giant Glacier

Researchers working in the Canadian high north have discovered two super-salty lakes buried deep beneath the Arctic ice. Untouched for thousands of years, the subglacial lakes may provide a tantalising glimpse into the kinds of alien life that might exist on Europa and Enceladus, two ice-covered moons in the far reaches of our Solar System.

Experiment Shows Microbes Could Thrive on Saturn’s Moon Enceladus

Enceladus is one of the most fascinating objects in the Solar System. Parked in orbit around Saturn, the ice-covered moon features a warm subterranean ocean and the basic chemical ingredients for life. But could alien microbes actually survive there? A new experiment suggests the answer is yes. Read More >>

TRAPPIST-1 Star System Contains Two Potentially Habitable Planets, New Study Suggests

It’s been less than a year since astronomers detected seven planets around TRAPPIST-1, a remarkable star system located 39 light years from Earth. New research suggests life could take root on at least two of these planets, thanks to a fortuitous orbital quirk. But other scientists aren’t so sure, saying TRAPPIST-1 still has much going against it in terms of its ability to foster life. Read More >>

Our Universe Could be Littered With Alien Viruses — and We Should be Looking for Them

It’s generally agreed that some kind of microbe will be the first form of life we discover on another planet, moon, or other space rock. But hardly anyone thinks we’ll find an alien virus, which is weird, given how prolific and successful these biological entities are on Earth. A new study seeks to correct this oversight, calling for an entirely new discipline known as “astrovirology.” Read More >>

How Aliens We’ve Never Met Could Help Humanity Escape Self-Destruction

Humans have had such a dramatic impact on Earth that some scientists say we’ve kickstarted a new geological era known as the Anthropocene. A fascinating new paper theorises that alien civilisations could do the same thing, reshaping their homeworlds in predictable and potentially detectable ways. The authors are proposing a new classification scheme that measures the degree to which planets have been modified by intelligent hosts. Read More >>

Hubble Observations Suggest Water May Be Abundant on Outer TRAPPIST-1 Planets

From the moment that seven Earth-sized planets were discovered in orbit around TRAPPIST-1—an ultracool dwarf star located 39 light years away—astronomers have been busy trying to learn everything they can about this intriguing star system, particularly its potential to foster life. Recently, an international team of scientists used the Hubble Space Telescope to assess the chances of water existing on these planets—and the results are promising. Read More >>

Massive Tides Could Boost TRAPPIST-1’s Prospects For Life

Earlier this year, Earthlings rejoiced when scientists announced the discovery of three rocky exoplanets in the habitable zone of TRAPPIST-1, an “ultracool dwarf” star located just 39 light years away. Soon after, astronomers brought us back down Earth, pointing out that it might be hard for life to survive on a world in such a tight orbit around such a dim star. But the debate has now taken yet another delicious twist, this time, in favour of aliens. Read More >>

Saturn’s Moon Enceladus Has Toxic Booze on its Breath

You think you have it rough because you spent the weekend eating tequila-soaked watermelon? That’s Juicy Juice compared to what Saturn’s moon Enceladus has been steeping itself in. Astronomers have spotted the organic molecule methanol surrounding the icy moon. Methanol, in case you forgot, is a highly toxic form of alcohol that can literally leave you blind—but after millions of years, we’d wager Enceladus’ tolerance is pretty high. Read More >>
