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 ...
A red giant star with one of the largest ranges in brightness known of stars in the night sky visible to the unaided eye. Despite its large radius, it is less massive than the Sun. 119 Tauri (CE Tauri, Ruby Star) 587 – 593 [76] AD ρ Cassiopeiae: 564 ± 67 or 700 ± 112 [77] AD
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
The James Webb Space Telescope has helped demystify the strange 2009 observation of a giant star about 25 times more massive than the sun that appeared to disappear from existence.
The R136a system at the core of R136 is a dense luminous knot of stars containing at least 12 stars, [11] the most prominent being R136a1, R136a2, and R136a3, all of which are extremely luminous and massive WN5h stars.
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 ...
For the first time ever, the Hubble Space Telescope spotted an individual main sequence star at 9 billion light-years away. That's just a couple billion years after the Big Bang.
The η Carinae star system is currently one of the most massive stars that can be studied in great detail. Until recently η Carinae was thought to be the most massive single star, but the system's binary nature was proposed by the Brazilian astronomer Augusto Damineli in 1996 [ 9 ] and confirmed in 2005.
