Until several years ago, most cinematic and artistic depictions of black holes — including many in the pages of Nature — failed to match the known facts. A black hole (the remnant of a runaway gravitational collapse) often looked like a space whirlpool, or perhaps a simple black sphere representing the event horizon — the surface that constitutes a point of no return for anything that falls inside. This would be pictured either against a background of stars, or surrounded by an ‘accretion disk’.

Things, they have changed...
