A supernova is a powerful and catastrophic stellar explosion that occurs at the end of a massive star's life cycle.
During a supernova, an immense amount of energy is released, sometimes outshining an entire galaxy for a short period of time.
Supernovae are vital for producing and scattering heavy elements like iron, gold, and uranium into space.
A supernova is a powerful and catastrophic stellar explosion that occurs at the end of a massive star's life cycle.
Supernovae can briefly outshine an entire galaxy, emitting more energy in a few weeks than the Sun will emit in its entire lifetime.
There are two main types of supernovae: Type I and Type II.
Type II supernovae happen when a massive star's core succumbs to gravity, collapsing rapidly and generating a powerful shockwave that disintegrates the star's outer layers.
Type II supernova remnants can give rise to neutron stars or black holes, determined by the collapsing core's mass.
Supernova explosions create expanding remnants in space
Humans have observed supernovae for centuries. A well-known example is SN 1054, which gave rise to the Crab Nebula.
Supernovae are vital for understanding the universe's expansion..
