Betelgeuse is a red supergiant star in the constellation of Orion.It is usually the tenth-brightest star in the night sky and, after Rigel, the second-brightest in its constellation.
The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.

One of the biggest and brightest stars in the night sky has left astronomers puzzled after it has faded dramatically over the last year. Some have speculated that this is a sign of an impending ...
Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star suggest it is both smaller — and closer — than astronomers ...
Models indicate that even rapidly rotating main-sequence stars should be braked by their mass loss so that red supergiants hardly rotate at all. Those red supergiants such as Betelgeuse that do have modest rates of rotation may have acquired it after reaching the red supergiant stage, perhaps through binary interaction. The cores of red ...
Betelgeuse as seen by ALMA. This is the first time that ALMA has observed the surface of a star and resulted in the highest-resolution image of Betelgeuse available. As stars of at least 0.4 M ☉ [85] exhaust the supply of hydrogen at their core, they start to fuse hydrogen in a shell surrounding the helium core.
The third vertex is Betelgeuse, which lies near the center of the hexagon. These three stars are three of the ten brightest objects, as viewed from Earth, outside the Solar System. Betelgeuse is also particularly easy to locate, being a shoulder of Orion, which assists stargazers in finding the triangle. Once the triangle is located, the larger ...
