Hubble Telescope Spies Strange 'Born-Again' Star After Epic Burn

A star's mysterious evolution recently came to light using the Hubble Space Telescope, which spotted the star cooling after a rapid temperature increase in the past. The researchers explained the process behind the rebirth of the star (called SAO 244567) in this new animation.
