UY Scuti (BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum. It is also a pulsating variable star , with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility.
UY Scuti: 909 [23] L/T eff: Initially reported 1,708 R ☉, making it the largest star, a 2023 measurement put the radius at a smaller value of 909 R ☉ based on the multimessenger monitoring of supernovae. [23] NR Vulpeculae: 908 [23] – 923 +62 −50 [25] L/T eff: KU Andromedae (IRC +40004) 900 [56] – 1,044 [55] L/T eff: V774 Sagittarii ...

HR 5171, also known as V766 Centauri, is a yellow hypergiant in the constellation Centaurus.It is said to be either an extreme red supergiant (RSG) or recent post-red supergiant (Post-RSG) yellow hypergiant (YHG), both of which suggest it is one of the largest known stars.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
A hypergiant (luminosity class 0 or Ia +) is a very rare type of star that has an extremely high luminosity, mass, size and mass loss because of its extreme stellar winds.The term hypergiant is defined as luminosity class 0 (zero) in the MKK system.

Vanover, a swing-arm contractor for United Space Alliance, fell to his death during preparations for a Space Shuttle mission.
Gaia BH1 (Gaia DR3 4373465352415301632) is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus. [4]
