|New super-Earth Habitable|
Astronomers have discovered another super-Earth in the "habitable zone" - meaning it could support liquid water and a stable atmosphere - around a nearby star, HD 40307. The previously discovered planets around it are called "hot super-Earths" because they orbit too close to the star to support life.
The new software "allows us to search deeper into the data and to find smaller Earth-sized planets around the nearest stars," said Paul Butler of the Carnegie Institution. "This, of course, increases our chances of finding more in that orbital sweet spot that we call the habitable zone—the zone where it is not too cold, nor too hot for liquid water to exist."
"The star HD 40307 is a perfectly quiet old dwarf star, so there is no reason why such a planet could not sustain an Earth-like climate," said Guillem Anglada-Escudé of the University of Göttingen.
