A home from home: Five planets that could host life
It's one of the big questions: Are we alone on this blue marble or is there life elsewhere in the cosmos? To shed some light, astronomers are searching for habitable worlds circling far-off stars.
A team has now published updated evidence for a planet that could be the most Earth-like yet. According to the US Planetary Habitability Laboratory, it would be the fifth potentially habitable world known outside our Solar System.
So what do we know about these five Earth-like planets, and how likely is it that they could support life?
