Astronomers have discovered a fascinating super-Earth planet in an exoplanetary system that will allow them to test the limits of habitability. Designated HD 20794 d, the planet follows a 647-day elliptical orbit that takes it from 0.7 to 1.5 astronomical units from the star. For half its orbit, it’s outside the habitable zone completely, then passes through the zone, reaching slightly inside the zone. Could life survive on a world like this?
