Alien Life Goes Extinct Early, According To A New Fermi Paradox Explanation

We have yet to discover a single trace of alien life, despite the extremely high probability that it exists somewhere. This contradiction is popularly known as the Fermi Paradox. A new theory attempts to solve this conundrum by suggesting that habitable planets are quite common in our galaxy, but nascent life gets snuffed out very quickly.

Astronomers Want To Build A 12 Metre Space Telescope To Find The Next Earth

With Pluto millions of kilometres behind us and construction of the James Webb Space Telescope moving swiftly along, astronomers are already thinking about the Next Big Mission. At the top of their wish list? A 12m-wide orbital telescope that will search for proof of life beyond Earth.

A Mesmerising Animation Shows Just How Weird Our Solar System Is

NASA’s Kepler space telescope spotted thousands of worlds during its four-year mission, proving that our galaxy is filled with planets. But even more surprising is what the Kepler database highlights about our own solar system: namely, that we’re a bunch of celestial oddballs.

The Fascinating Reason Multi-Planet Star Systems Might Harbour Life

Living on Earth, without a single other habitable world in eyeshot, can sometimes feel pretty lonely. But our isolation may be the cosmic exception. In fact, it’s possible that throughout the galaxy, life-bearing worlds usually come in pairs.

The Five Most Earth-Like Exoplanets (So Far)

I’ve lost count of the number of times I’ve read that the “first Earth-like exoplanet” has been discovered. With nearly 2000 exoplanets found to date, it is no wonder so many of them will resemble our planet in some way. But which exoplanets are similar enough to the Earth that they could actually be habitable?

This Is The First Time We've Witnessed A Planet Forming

Four and a half billion years ago, a whirling cloud of cosmic dust condensed into the lump of rock we call home. For the first time, astronomers are now watching that same planet-forming process playing out around a distant star.

This Visualisation Shows The Astonishing Diversity Of Alien Worlds

Slovak graphic designer Martin Vargic has pieced together a rather meticulous visualisation showing over 500 exoplanets discovered by astronomers as of October 2015. Like snowflakes, it shows that no two planets are the same.

The Closest Exoplanet To Earth Was Probably A Ghost

When the exoplanet Alpha Centauri Bb was announced in Nature in 2012, it was hailed a watershed moment in the search for Earth-like worlds beyond our solar system. But as eerie as it sounds, it now appears that Alpha Centauri Bb never existed.

Aliens Or Not, There's Still A Lot To Discover In NASA's Kepler Data

This week, the internet worked itself into a frenzy over the possibility that we’ve found an alien megastructure. But whether or not there’s a Dyson sphere buried in the Kepler data, the discovery of a strange, flickering star is very interesting.

Astronomers Want To Watch Comets Slam Into Distant Planets

If a massive comet struck the Earth, the oceans would boil and the air would catch fire (don’t worry, this isn’t about to happen). But to alien astronomers studying our planet from afar, humanity’s brutal demise would look like nothing more than a faint flicker of light. If we could detect such impacts on distant worlds, we might learn a lot about their star systems.
