Astronomers have discovered that our nearest big neighbour, the Andromeda galaxy, is roughly the same size as the Milky Way. It had been thought that Andromeda was two to three times the size of the Milky Way, and that our own galaxy would ultimately be engulfed by our bigger neighbour. But the latest research, published today, evens the score between the two galaxies.

An international team of astronomers has used two of the world's largest radio telescopes to show that a mysterious source of radio bursts is in an astonishingly extreme and unusual environment. The discovery suggests that the strange source is in close proximity to a massive black hole, or within a nebula of unprecedented power.
