Supernova News

A supernova is a powerful and luminous stellar explosion that occurs at the end of a star’s life cycle, typically triggered in one of two ways. The first involves a massive star exhausting its nuclear fuel, leading to a core collapse under the force of gravity, and a subsequent violent explosion. The second type occurs in a binary star system where a white dwarf star accumulates material from its companion star until it reaches a critical mass and undergoes a thermonuclear explosion. Supernovae are among the universe’s most energetic events and play a crucial role in galactic evolution, dispersing heavy elements necessary for new stars and planets into space. The brightness of a supernova can briefly outshine an entire galaxy and can be visible from great distances, providing critical information about the universe’s expansion and the interstellar medium’s composition.
