Circumstellar dust disk around Beta Pictoris (more).
Beta Pictoris (β Pic / β Pictoris) is the second brightest star in the constellation Pictor.
Beta Pictoris b imaged in 2003 (left image), October 2009 (middle) and in March 2010. The planet's motion is clearly seen between 2003 and 2009. Published in Astronomy & Astrophysics, 2011, vol. 528, L15.
HST has observed Beta Pictoris (right) and found the disk to be significantly thinner than previously thought.

Some bright stars in our sky have dust around them: Vega, Beta Pictoris, and Fomalhaut. These are systems possibly in the beginning stages of forming planets.
Still, the disk around one of these stars, called Beta Pictoris, has been photographed by two astronomers using specialized electronic detectors and a large telescope atop a Chilean mountain.

IRAS, which performed an all-sky survey in infrared, as well as discovering disks of dust and gas around many nearby stars, such as Fomalhaut, Vega and Beta Pictoris. This ceased functioning in 1982 and has since re-entered the atmosphere.
The radiation is coming from a huge circular shell of dust surrounds the star extending outwards to 140 AU in radius, much like those that encompass Fomalhaut, Beta Pictoris, and Denebola.
Fomalhaut is a bluish white star, younger than our Sun and is located about 25 light years away. It's surrounded by a warped disk formed from icy dust particles similar to that around Vega, Beta Pictoris and Denebola.

All of this has caused planetary scientists to revisit accepted theories of planetary formation. Future theories will be measured against stars surrounded by a ring of gas and dust, such as Beta Pictoris, ...
