Astronomers found two renegades, runaway white dwarf stars on an escape route out of our galaxy. These runaway stars are on a one-way ticket out of our galaxy. Runaway stars racing away at breakneck speedsIn the new study, astronomers using data from the European Space Agency's Gaia survey identified two runaway stars with the fastest radial velocities ever seen. Two white dwarf stars orbiting each other can trigger an especially enormous explosion called a D^6 supernova. The first explosion kicks off when one of the white dwarf stars accumulates too much helium gas, which triggers a thermonuclear explosion, reported Starr.
