Supermassive Black Hole
This space animation was commissioned by National Geographic magazine for an article entitled 'The Truth about Black Holes'. It shows a supermassive black hole at the centre of the Milky Way galaxy, shredding and consuming a passing cloud of gas, and...

Binary Black Hole Merger
Illustration of two black holes orbiting each other in a combined accretion disc. Eventually the black holes will merge, an event that will produce gravitational waves. Gravitational waves are a prediction of Einstein's theory of general relativit...

Black Hole Space Warp
Black holes are objects so massive and compact that nothing can escape from them, including light. They distort the spacetime around them, somewhat like a heavy ball on a stretchy rubber sheet, as this conceptual illustration shows...

Blues for a Dead World
Here you have an impression of a high-mass x-ray binary (HMXB), in which a blue giant (right) orbits a compact object such as a neutron star or black hole. The blue giant has a powerful stellar wind, shown radiating outwards here. Some of this materi...

Cosmic Gusher
Active galaxies, such as this one, are commonplace in the Universe. Quasars are an example. Astronomers think that all active galaxies are driven by the same engine: a supermassive black hole with the mass of at least a few million solar masses. As m...

Cygnus X-1
Cygnus X-1 is a very famous x-ray binary star system. It consists of a giant blue star (top) in orbit around what in all likelihood is a – wait for it – black hole. The black hole steals gas from its giant companion and that gas flows towards the...

High-Mass X-Ray Binary
This is an animation of a high-mass x-ray binary, in which a giant blue star is in orbit around a compact companion – sometimes a neutron star and sometimes a black hole. The giant star is distorted owing to its proximity to its highly compact part...

Low-Mass X-Ray Binary II
This image shows a low-mass x-ray binary star seen from a nearby, hypothetical asteroid field. The system consists of a red dwarf (bottom) which is losing its atmosphere to a black hole via an accretion disc....

Be X-Ray Binary
Here is a different kind of x-ray binary. In the foreground (top) is a hot star called a Be star. It spins so quickly that it is surrounded by a circumstellar disc of matter, flung off via centrifugal force. The Be star is in orbit around a tiny and ...

Bubble Universes
This is a conceptual representation of the baby universes idea: where our Universe is linked to an infinite number of others via bridges called wormholes, and each of these other universes is itself linked to others....
