Although the star is much younger than the Sun, it is twice as massive and nine times more luminous. Optical images (0.5 microns) show the disk because dust reflects light from the central star and towards the observer. Explanation: A mere 50 light-years away, young star Beta Pictoris became one of the most important stars in the sky in the early 1980s. Beta Pictoris is located 63 light-years away in the southern constellation Pictor. The object was initially found around eight AUs from Beta Pictoris within the relative central void (which has a diameter around 50 AUs) of the star's circumstellar dust disk. Beta Pictoris entered the limelight over 20 years ago when NASA's Infrared Astronomical Satellite detected excess infrared radiation from the star. The bright star beta Pictoris is visible in the Southern Hemisphere and has the brightest, most extended dust disk of any nearby star. This little satellite will investigate a curious star and its planet. Beta-Pictoris is a bright star seen in Southern sky. This artist's view shows the planet orbiting the young star Beta Pictoris. It is the second brightest star of the Pictor constellation, hence its designation Beta, the second letter of the Greek alphabet.Pictor is the abbreviation of Equuleus Pictoris, or the Painter's Easel,.Beta-Pictoris is somewhat bigger and brighter than the Sun.
