Astronomers have recently discovered a potentially habitable planet about 20 light years away from Earth! It orbits a red dwarf star and has been given the name Gliese 581g, but is more commonly called Zarmina's World (named after the wife of the astronomer who made the discovery). Zarmina's World has a 37 day orbit and a mass 3.1 times bigger than Earth's. This amazing discovery indicates that there may be many other habitable planets in just the Milky Way alone! It makes you think about the fact that Earth could very possibly be not the only planet with life.
