The list specifically excludes both white dwarfs – former stars that are now seen to be "dead" but radiating residual heat – and black holes – fragmentary remains of exploded stars which have gravitationally collapsed, even though accretion disks surrounding those black holes might generate heat or light exterior to the star's remains ...
The observable universe contains as many as an estimated 2 trillion galaxies [36] [37] [38] and, overall, as many as an estimated 10 24 stars [39] [40] – more stars (and, potentially, Earth-like planets) than all the grains of beach sand on planet Earth. [41] [42] [43] Other estimates are in the hundreds of billions rather than trillions.
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
The most famous elliptical galaxy is M87, which has up to 2.4 trillion stars. Astronomers recently used a combination of special telescopes to image the center of M87 and the supermassive black ...
Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy in the constellation Virgo that contains several trillion stars.
The following are lists of stars. ... List of star systems within 150-200 light-years; ... — second most distant star, 9 billion light years away. [1] [2]
Typical galaxies range from dwarfs with as few as ten million [110] (10 7) stars up to giants with one trillion [111] (10 12) stars. Between the larger structures are voids, which are typically 10–150 Mpc (33 million–490 million ly) in diameter. The Milky Way is in the Local Group of galaxies, which in turn is in the Laniakea Supercluster ...
