‘Tens of billions’ of potentially habitable planets in our galaxy


Scientists have long assumed that the best chance of finding alien life in the universe is on planets similar to ours. The latest scientific discoveries show that there might be tens of billions of such planets in our galaxy alone.

­Astronomers at the European Southern Observatory in Chile came to these findings after studying more than a hundred red dwarves, the most common stars in the universe.

The French-led team found out that 40 per cent of red dwarves are orbited by super-Earths – planets up to ten times bigger than our own – which are the correct distance away from their star for liquid water to be found on them. Liquid water is considered a major precondition of life.

From then on, figuring out the amount of potentially habitable planets was only a matter of math.
