Escape velocity: 2,000 kilometers per second – Research from the Technion reveals the origin of the fastest white dwarfs in the galaxy

A team of researchers led by Dr. Hila Glantz and Prof. Hagai Peretz from the Technion found that a merger between special white dwarfs leads to a dramatic double explosion, leaving behind the remnants of stars that fly at dizzying speeds beyond the boundaries of the Milky Way.
