Generally speaking, black holes are the corpse of a dead star. But not all stars become black holes at the end of their life – for instance, our familiar Sun is small enough to avoid that fate. Until recently, black holes were thought to be formed only by super-massive stars, and the smallest black hole known to scientists was about five times the mass of the Sun. However, a recent scientific paper has announced the discovery of a black hole much smaller than that. This would require astronomers to rethink their models of black hole formation, because black holes shouldn’t be so small.
