Researchers peering at the Universe’s first-born stars have uncovered the key to predicting a star’s destiny.
Stars that don’t have enough mass never shine, dying billions of years before their bigger counterparts.

Reporting in the journal Science, astronomers have viewed high quality pictures of some of the faintest stars in our galaxy for the first time.
