Two Dying Stars Reborn as One

CfA astronomers have found a pair of white dwarf stars orbiting each other once every 39 minutes. In a few million years, they will merge and reignite as a helium-burning star. In this artist’s conception, the reborn star is shown with a hypothetical world. An accompanying animation shows the merger process.
