A white dwarf star has been detected hurtling through the Milky Way at 560,000 miles per hour thanks to a thermonuclear blast from a partial supernova. Researchers from the University of Warwick used data from the Hubble Space Telescope to figure out what sent the white dwarf on its mission. The white dwarf has an ‘amazing atmospheric composition’ that implies it was a binary star that was able to withstand a supernova outburst and was thrown out of the system with its pair going in the opposite path. The new study opens up the hope of many more survivors of supernovae traveling undiscovered through the Milky Way.
