Cosmic dust disc to force rethink

The discovery of a large disc of dust around a binary star system could force astronomers to rethink their computer models of the Universe.

Previous observations turned up no sign of the disc at WZ Sagittae.

But data from Nasa's Spitzer infrared telescope confirmed there was much more to this object than previously thought.

The discovery may have implications for the study of everything from supermassive black holes to the formation of planets.

They were able to detect a dust disc around a brown dwarf star in a binary star system in our galaxy using infrared telescopes. Infrared is used to detect gas and dust clouds. The more they look, the more discs they see. Not only does the dust disc relate to how the system behaves because of its mass, the discs my be involved with the formation of planets and other bodies in ways not previously understood.
