Out in our universe, large galaxies rip smaller ones to pieces and white dwarfs feed on healthy young stars. Welcome to the wild world of galactic cannibalism.
Are Star ‘Crumbs’ Evidence of Galactic Cannibalism?
“Stars discovered in the Milky Way’s halo could be what remains of smaller galaxies that were eaten to form the our galaxy.”
Milky Way Has 4 Billion Years to Live — But Our Sun Will Survive
“Four billion years from now, our galaxy, the Milky Way, will collide with our large spiraled neighbor, Andromeda. The galaxies as we know them will not survive.”
Stellar cannibalism transforms star into brown dwarf
“Due to their close proximity, the white dwarf strips mass from its low-mass companion. This process has removed about 90 per cent of the mass of the companion, turning it from a star into a brown dwarf.”
