There May Be An Earth-Like Exoplanet Less Than Five Light Years Away

Rumours are flying that astronomers at the European Southern Observatory have discovered an Earth-like exoplanet in the habitable zone of Proxima Centauri, our nearest neighbouring star. If confirmed, this is undeniably one of the biggest astronomical discoveries of the century.


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?


The 20 Most Earth-Like Exoplanets We've Found

Kepler has given us a stash of thousands of exoplanets. Now, researchers have pulled 20 from that stash that they say are the most likely to be habitable.


One Of The Best Explanations For Why We Haven't Found Alien Life

So far, the only examples of sentient life we’ve found are right here on our own planet. It’s not for lack of trying, though — we’ve sent out spacecraft deep into the reaches of our galaxy and, so far, still remain alone. What if the problem isn’t where where looking, though, but when?


Mission Hopes To Find The 'Goldilocks Zone' In Our Closest Galactic Neighbour

Exoplanets are all the rage nowadays thanks in part to Kepler’s discovery of around 1284 previously undiscovered planets and our never-ending fascination with the “final frontier” that just seems to be moving closer to a reality. But out of the thousands of planets that we know of, how many are set to support life?


How Often Does Life Emerge In The Universe?

Since the 1960s, the Drake Equation has been used to predict how many communicative extraterrestrial civilisations exist in the Milky Way galaxy. Along these same lines, a new formula seeks to estimate the frequency at which life emerges on a planet — a calculation that might allow us to figure out the likelihood of life arising elsewhere in the universe.


Incredible Photo Shows An Exoplanet In Orbit Around Its Host Star

See that tiny speck just to left of the bluish orb? That’s a planet. It’s one of the best direct images of an exoplanet we’ve ever seen, and it’s made all the more remarkable given that it’s a whopping 1200 light-years away.


Astronomers Might Have Just Solved A Key Mystery About The Origin Of Life

If a massive solar storm struck the Earth today, it could wipe out our technology and hurl us back to the dark ages. Lucky for us, events like this are quite rare. But four billion years ago, extreme space weather was probably the norm. And rather than bringing the apocalypse, it might have kickstarted life.


Our Solar System Could Remain Habitable Long After Earth Is Destroyed

In a few billion years, the oceans will boil away and the atmosphere will burn up as our sun expands into a red giant. It will be game-over for life on Earth, but in the outer solar system, the party will just be getting started. Europa and Enceladus will melt into ocean moons, offering a refuge for any post humanoid life forms fleeing their lava-soaked homeland.


A Huge Unnamed Dwarf Planet, Almost The Size Of Pluto, Has Been Hiding In Our Solar System

Image: Artist’s concept of 2007 OR10 / NASA In a universe full of planets, 2007 OR10 is something special. It’s big, just slightly smaller than the size of Pluto. And it’s close, within our very own solar system. So how did it still manage to take astronomers by surprise?
