Barnard-b is discovered to be a new potential home for simple alien lives said by scientists Edward Guinan and Scott Engle. It is the nearby world rotating around the Barnard Star which is the second closest star system to Earth. It has a minimum of 3.2 Earth masses.

It was first discovered as a very cold planet with a temperature of minus 170 degrees Celsius that could instantly kill any organism. Light and water are also barely present there. However, the recent findings showed that the planet has tidal heating underneath that can make it livable. This was announced at the 233rd meeting of the American Astronomy Society (AAS).
