Supernova - Wikipedia
Supernovae can expel several solar masses of material at speeds up to several percent of the speed of light. This drives an expanding shock wave into the surrounding interstellar medium, sweeping up an expanding shell of gas and dust observed as a supernova remnant.
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.
What Is a Supernova? | NASA Space Place – NASA Science for Kids
A supernova of a star more than about 10 times the size of our sun may leave behind the densest objects in the universe— black holes. The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away.

A supernova is what happens when a star has reached the end of its life and explodes in a brilliant burst of light.
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.
Scientists mapped the shape of a supernova for the first time ever ...
Astronomers using data from the Very Large Telescope (VLT) have revealed that the initial "breakout" phase of a supernova is elongated, not perfectly spherical.
What is a Supernova? Exploring the Explosive Death of Stars and Its ...
A supernova is not just a star’s death—it is a dramatic event that reshapes the cosmos. These cosmic explosions are responsible for creating the elements that make up the Earth and life itself, and they play a critical role in the evolution of galaxies and stars.
What is a supernova? - EarthSky
A supernova is a star's colossal explosion at the end of its life, which can outshine its entire galaxy. Read about causes and types of supernovae here.
Scientists reveal true shape of exploding supernova – and it ... - MSN
The supernova’s progenitor was a red supergiant star, with a mass 12 to 15 times that of the Sun and a radius 500 times larger, making SN 2024ggi a classical example of a massive-star explosion.
What is a Supernova? Definition, Causes, Types of Supernova Explosions ...
If a very nearby star goes supernova, it can genetically alter or possibly even destroy life on Earth. Even a fairly distant one often leaves visible wreckage that makes us telescopically gawk at what very much resembles a disastrous event.
