To find other exoplanets that might be like Earth, astronomers tune their telescopes to the ‘Goldilocks region’ around a star.
This is the habitable zone that is far enough away from the star so the planet’s surface isn’t scorched like Venus, but close
enough that it isn’t freezing like Mars. Astronomers have found over 40 exoplanets in Goldilocks regions to date (a small fraction
of the thousands of exoplanets that have been discovered), but according to new research coming out of Yale, this doesn’t necessarily
tell us anything about their ability to support life.
