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.
May 6, 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.
May 25, 2024 · 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.
Jun 19, 2023 · A supernova is what happens when a star has reached the end of its life and explodes in a brilliant burst of light. Supernovas can briefly outshine entire galaxies and radiate more energy than...
3 min read. Some stars burn out instead of fading. These stars end their evolutions in massive cosmic explosions known as supernovae. When supernovae explode, they jettison matter into space at...
Mar 14, 2023 · NASA’s Webb Telescope Captures Rarely Seen Prelude to Supernova. NASA Webb Telescope Team. Mar 14, 2023. Article. The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022.
Nov 8, 2023 · Here is a brief description of the main categories of exploding stars. By Jake Parks | Published: November 8, 2023 | Last updated on November 17, 2023. An artist's impression of how a type Ia...

Sep 8, 2023 · IC 1776 recently played host to a catastrophically violent explosion – a supernova – which was discovered in 2015 by the Lick Observatory Supernova Search, a robotic telescope which scours the night sky in search of transient phenomena such as supernovae.
Mar 26, 2018 · By understanding supernovae, scientists can unlock mysteries that are key to what we are made of and the fate of our universe. But to get the full picture, scientists must observe supernovae from a variety of perspectives, especially in the first moments of the explosion.
