Some of them will likely be in the so-called habitable zone, where the temperatures are just right for liquid water.
The results suggest that the current definition of "habitable zone" may be too simplistic.
The habitable zones of the cosmos are vast, it seems, and they may be teeming with life.
That means the habitable zone could be a lot wider, and the prospects for alien life more favorable, than anyone thought. (See pictures of the Hubble telescope's greatest hits.)
That would be a depressing end to the story of habitable zones, if not for a series of amazing findings that life on Earth is not what everyone thought it was.
At the right distance, they would be in a newly expanded habitable zone around the swelled-up star.
Because if you found one in the habitable zone, would that mean it had life?
