Supernova | Definition, Types, & Facts | Britannica
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.
Supernova - Wikipedia
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.

A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
What is a supernova? | Space
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...
NASA, Global Astronomers Await Rare Nova Explosion
Don’t confuse a nova with a supernova, a final, titanic explosion that destroys some dying stars, Hounsell said. In a nova event, the dwarf star remains intact, sending the accumulated material hurtling into space in a blinding flash.
What is a supernova? - EarthSky
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 of...
Supernovas & Remnants - Harvard–Smithsonian Center for Astrophysics
Supernovas are some of the brightest events in the universe, occasionally outshining entire galaxies at their peak. Many supernovas can be seen from billions of light-years away, and nearby supernovas in past centuries have been visible during the daytime.
Supernovae Information and Facts | National Geographic
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...

What Is a Supernova? - Definition and Astronomical Facts
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.
