A supernova (pl.: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion.
Nov 8, 2024 · A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. An illustration of one of the brightest and most energetic supernova explosions ever recorded. Image credit: NASA/CXC/M.Weiss.
6 days ago · supernova, any of a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level. The term supernova is derived from nova (Latin: “new”), the name for another type of exploding star. Supernovae resemble novae in several respects.

Nov 12, 2020 · A supernova is the name given to the cataclysmic explosion of a massive star at the end of its life. It can emit more energy in a few seconds than our sun will radiate in its lifetime...
Oct 19, 2023 · A supernova is a star that has reached the end of its life and has exploded. The light from a supernova can be seen from billions of light years away and is so bright that it can outshine an entire galaxy. Supernovae are important because they help create new elements and distribute them throughout the universe.
A supernova is the colossal explosion of a star. Scientists have identified several types of supernova. One type, called a “core-collapse” supernova, occurs in the last stage in the life of massive stars that are at least eight times larger than our Sun.
The supernova phenomenon is characterized by an increase in the brightness of the star by 4-8 orders of magnitude and its slow decay, as well as a large release of energy as a star explodes. However, since their registration is carried out on the ground, it means that everything is over.
