It is a type of massive star called a red supergiant. "Its estimated mass means it has lived for about 10 to 20 million years, and will soon die," van Loon said.
Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision; Solar flares are a minor type of stellar explosion [1] Tidal disruption event, the pulling apart of a star by tidal forces
Stars far more massive than the sun evolve in complex ways. In the core of the star, hydrogen is fused into helium, releasing thermal energy that heats the star's core and provides outward pressure that supports the star's layers against collapse – a situation known as stellar or hydrostatic equilibrium. The helium produced in the core ...
New James Webb Space Telescope (JWST) images of a supernova's keyhole could unlock mysteries of exploding stars, according to astronomers. Images revealed previously unseen crescent-like ...
The layers of a massive, evolved star just before core collapse (not to scale) Very massive stars can undergo core collapse when nuclear fusion becomes unable to sustain the core against its own gravity; passing this threshold is the cause of all types of supernova except type Ia.
A new window on the universe was opened when gravitational waves were detected for first time from the collision of two black holes in 2015.
In this case, a massive star (>30 solar masses) collapses to form a rotating black hole emitting twin astrophysical jets and surrounded by an accretion disk. It is a type of stellar explosion that ejects material with an unusually high kinetic energy, an order of magnitude higher than most supernovae, with a luminosity at least 10 times greater.
Astronomers have performed a great number of studies on collapsing stars, but capturing one in the optical wavelength or visible light during the early moments of explosion has proven elusive.
