It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
R136a1 (short for RMC 136a1) is one of the most massive and luminous stars known, at nearly 200 M ☉ and nearly 4.7 million L ☉, and is also one of the hottest, at around 46,000 K. It is a Wolf–Rayet star at the center of R136 , the central concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula (30 Doradus ) in ...
The first stars in the universe are thought to have been considerably brighter and more massive than the stars in the modern universe. Part of the theorized population III of stars, their existence is necessary to explain observations of elements other than hydrogen and helium in quasars .
A yellow hypergiant, one of the rarest types of stars. V838 Monocerotis: 464 [81] L/T eff: During the 2002 Red Nova, the star's radius may have increased up to 3,190 R ☉. [82] Pistol Star (V4647 Sagittarii) 420 [83] L/T eff: One of the most luminous stars known. La Superba (Y Canum Venaticorum) 344 [84] L/T eff: Mira (ο Ceti A) 332–402 [85] AD
It is a type of massive star called a red supergiant. ... "We found out that WOH G64 has changed its appearance noticeably in the last 10 years," Ohnaka said, adding that it was becoming dimmer ...
A black hole (artist concept); Vela Pulsar, a rotating neutron star; M80, a globular cluster, and the Pleiades, an open star cluster; The Whirlpool galaxy and Abell 2744, a galaxy cluster; Superclusters, galactic filaments and voids
Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars. Astronomers just discovered one of the most massive objects in the universe hiding behind the Milky ...
Earlier observations found that, if placed at the center of our solar system, the massive star Betelgeuse would stretch out beyond the orbit of Jupiter. This new study finds its body would only ...
