noun a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass
A supernova is a powerful and luminous stellar explosion that occurs when a star reaches the end of its life cycle, either through a sudden increase in nuclear fusion or by gravitational collapse.
Supernovae play a crucial role in the evolution of galaxies and the dispersal of elements necessary for the formation of planets and life.
Studying supernovae can provide insights into the expansion of the universe and the nature of dark energy.
The energy and radiation from supernovae can impact the habitability of planets in their vicinity.
The intense energy released during a supernova can lead to the formation of new elements through nucleosynthesis.
Astronomers study supernovae to better understand the life cycle of stars and the processes involved in stellar explosions.
Physicists use data from supernova observations to study the expansion of the universe and the nature of dark energy.
Astrophysicists research supernovae as a way to investigate the properties of neutron stars and black holes.
Science communicators often use supernova events as a way to engage the public in discussions about the vastness and complexity of the universe.
Science fiction writers may incorporate supernovae into their stories as dramatic events that can have far-reaching consequences for characters and civilizations.
Science teachers use supernovae as examples to explain concepts such as nuclear fusion, stellar evolution, and the formation of heavy elements in the universe.
