If you have any leftover hard-boiled eggs, you can recreate this bit of fluid dynamical fun. Spin the egg through a puddle of milk, and you'll find that the egg draws liquid up from the puddle and flights it out in a series of jets. As the egg spins, it drags the milk it touches with it.

The black hole in question resides 60 million light years away at the centre of the NGC 1365 spiral galaxy, is a mind-boggling 3.2 million kilometres in diameter, has a mass two million times that of our Sun and is spinning at a rather impressive 1.08 billion km/h. Astronomers can now say this with confidence, after combining the efforts of Nasa's Nuclear Spectroscopic Telescope Array (Nustar) — which measures high-energy X-rays — and the European Space Agency's XMM-Newton, which measures low-energy X-rays.
