Astronomers discovered a new population of ultra-fast-moving stars, including the fastest 'runaway' star ever seen in our galaxy.
Astronomers have detected the fastest runaway star ever seen in the Milky Way galaxy — the husk of a star launched at blistering speeds from a gigantic cosmic explosion.
But a simple star explosion isn't enough to launch stars at this speed. Astronomers suspect that hypervelocity stars are sent flying by a special kind of Type Ia supernova called a dynamically driven double-degenerate double-detonation supernova. Despite the apparent abundance of these powerful supernovas, evidence for them and the white dwarfs they fire like bullets remains hard to find. To search for some candidates, the researchers turned to the Gaia star catalog, an ongoing project with the goal of creating the most detailed star map of our galaxy ever made.

Astronomers discover 2nd-ever 'Tatooine' star system with multiple planets orbiting multiple sunsHarry is a U.K.-based staff writer at Live Science. He studied Marine Biology at the University of Exeter (Penryn campus) and after graduating started his own blog site 'Marine Madness,' which he continues to run with other ocean enthusiasts. He is also interested in evolution, climate change, robots, space exploration, environmental conservation and anything that's been fossilized. When not at work he can be found watching sci-fi films, playing old Pokemon games or running (probably slower than he'd like).
