An Ambitious Search for Aliens Came Up Short, so Astrobiologists Are Thinking Bigger

The Breakthrough Listen project has completed a sweeping search of over 1,700 nearby stars for signs of alien technology. Sadly, no evidence of extraterrestrials was found, but the $100 million project took a major leap forward in terms of its ability to continue the search. Read More >>

The Hidden Ocean Beneath Europa’s Frozen Crust May Contain Basic Table Salt

Observations from the Hubble Space Telescope point to the presence of sodium chloride on the surface of Jupiter’s icy moon Europa. This is potential evidence that sodium chloride, otherwise known as table salt, exists within Europa’s subsurface ocean – yet another indication of this moon’s potential to support alien life.

An Astounding Amount of Water Has Been Discovered Beneath the Martian North Pole

Using ground-penetrating radar, scientists detected a massive reservoir of frozen water sandwiched by layers of sand beneath the northern polar ice cap on Mars. This reservoir contains so much ice that, if melted and brought to the surface, it would submerge the entire planet. Read More >>

Simulated Mission in Chilean Desert Shows How a Rover Could Detect Life on Mars

By using the barren Atacama Desert in Chile as a stand-in for Mars, researchers have shown that it’s possible to use an autonomous rover-mounted drill to detect life beneath a desolate surface. Encouragingly, the test resulted in the discovery of a resilient microorganism – exactly the kind of creature that could lurk deep beneath the Martian surface. Read More >>

A Guide to the Chemistry of Cold Weather

You might have noticed that it’s pretty cold at the moment – frostbite-inducing, school-closing, scald-yourself-with-boiling-water-while-attempting-that-stupid-instant-snow-trick cold. You might wonder what that means, scientifically. Read More >>

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 >>
