The planet, visible as a bright dot in the lower right of the frame, is ten times as massive as Jupiter and orbits the pair at times the distance Jupiter orbits the Sun. The other bright dot in the image top right is a background star. By taking different images at different times, astronomers were able to distinguish the planet from the background stars.

Giant planet at large distance from sun-like star puzzles astronomers Apr 19, Oct 02, Jan 12, SPHERE has successfully imaged several planets orbiting stars other than the Sun before, including taking the first ever-image of two planets orbiting a Sun-like star.
As part of their study, the team looked into archival data on the b Centauri system and discovered that the planet had actually been imaged more than 20 years ago by the ESO 3.

ScienceDaily, 8 December ESO telescope images planet around most massive star pair to date. Retrieved January 13, from www. Featured Content. The hydroxyl radical OH was found on the dayside of Images of systems with multiple exoplanets are Around the young star AB Aurigae lies a dense If this planet were somehow placed into our own solar system, it would Located approximately light-years away in the constellation Centaurus, the b Centauri two-star system also known as HIP has at least six times the mass of the Sun, making it by far the most massive system around which a planet has been confirmed.
Until now, no planets had been spotted around a star more than three times as massive as the Sun. Most massive stars are also very hot, and this system is no exception: its main star is a so-called B-type star that is over three times as hot as the Sun. Owing to its intense temperature, it emits large amounts of ultraviolet and X-ray radiation. This is the most massive and hottest planet-hosting star system found to date. The planet is ten times as massive as Jupiter and orbits the two-star system at times the distance Jupiter orbits the Sun.
The large mass and the heat from this type of star have a strong impact on the surrounding gas, that should work against planet formation. In particular, the hotter a star is, the more high-energy radiation it produces, which causes the surrounding material to evaporate faster. But the new discovery shows planets can in fact form in such severe star systems.
