Forget “Earth-Like”—We’ll First Find Aliens on Eyeball Planets
Artist’s conception of a hot Eyeball planet. The permanent day side is sun-baked and dry. The permanent night side is covered with ice. In between lies a thin habitat: the ring of life.Illustration by Beau.TheConsortium Imagine a habitable planet orbiting a distant star. You’re probably picturing a variation of Earth.

What Do Romantic Aliens See at the End of Their Alien Days?
When it comes to exoplanets, reality is catching up with science fiction. Take Kepler-16b, a Saturn-size planet roughly 200 light-years from Earth that circles not just one star but a pair of stars.

Maybe the trees are red instead of green. Maybe there are scantily clad natives … OK, let’s stop there. That image may very well […]
What Earth Tells Us About Life, Intelligence & the Universe

But for some hardened naysayers, Astrobiology’s glamour is tainted by that […]
Where Could You Find the Best Surfing in the Universe?
As recently as the late 80s, finding a planet orbiting another star seemed like the stuff of sci-fi fantasy, about as realistic as a diminutive alien riding a flying bicycle, or a sports car that worked as a time machine. Thanks to many smart astronomers using a new generation of powerful telescopes, we now know […]
When a Planet Is Not Really a Planet at All
As astronomers point their telescopes up at the sky to learn about the cosmos, they tend to push those devices’ abilities to their limits. The edge of what we can measure is, of course, where all the interesting things are happening. The downside of this ambition is that the conclusions drawn from the newest data […]
