Fomalhaut is sometimes called the Loneliest Star. Its planet Fomalhaut b was the first beyond our solar system to be visible to the human eye.

New research from scientists at the University of Rochester reveals that the Fomalhaut star system contains a third star, Fomalhaut C. The nearby star system Fomalhaut – of special interest for its unusual exoplanet and dusty debris disk – has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known.

Finding Exoplanets: Direct Imaging This one is pretty self-explanatory. Powerful telescopes get actual images of distant worlds, using instruments called coronagraphs to block out the overwhelming glare of their parent stars.

Fomalhaut is sometimes called the Loneliest Star. Its planet Fomalhaut b was the first beyond our solar system to be visible to the human eye.

The Fomalhaut system contains a cleared ring (shining brightly in this image) in the dust around the star. Scientists suspect that this gap was cleared by a pair of terrestrial planets, but new research reveals that the presence of gas could also create such a breach.
