These are called ellipitical galaxies
Massive stars that are at least eight times more massive than the Sun end their life as a supernova. During the explosion, these stars release a tremendous amount of energy and can briefly outshine an entire galaxy.
An elliptical galaxy is a type of galaxy not a particular one.
Massive
Large Spiral Galaxy. This is because they contain more of the OB stars that are required for a supernova event. Elliptical galaxies tend to be older and have more low mass stars and are not as common as spiral galaxies. See Link for more information
The most abundant type of stars is red dwarves.
The spiral galaxy's.
O-type stars are the most massive and hottest types of stars that form relatively recently in the Milky Way galaxy. These stars have short lifespans of a few million years before they burn out, so any O-type stars still observed today are relatively young in astronomical terms.
a spiral galaxy like the milky way
blob is blob and blob.
Typically irregular galaxies have the oldest stars
The most massive main sequence stars are typically blue in color, due to their high surface temperatures. These stars are known as O-type stars and can be tens of times more massive than the Sun.
No. A supernova is a massive explosion, usually from a dying supermassive star.
