Stars live and die on epic time scales. Tens of millions of years, hundreds of millions of years, even billions of years or longer. Maybe the only thing that surpasses that epicness is when two dead stars join together and come back to life.
Astronomers at the University of Bonn in Germany, along with colleagues in Russia, have spotted a very bizarre star that may have formed when two dead stars came back to life. The star was first spotted by Russian astronomers in images from the Wide-field Infrared Survey Explorer (WISE) satellite. They've named the star J005311.
