How would you describe a supernova?
A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star.
What does it mean to go super nova?
Supernova
Supernova is an astronomical term for a star that explodes like crazy. When a star turns into a supernova, it becomes extremely bright. Supernova sounds like a superhero, but it refers to the super explosion of a star. A nova is also the explosion of a star, but a supernova has more energy.
What is a supernova and what causes it?
It’s a balance of gravity pushing in on the star and heat and pressure pushing outward from the star’s core. When a massive star runs out of fuel, it cools off. This causes the pressure to drop. The collapse happens so quickly that it creates enormous shock waves that cause the outer part of the star to explode!
Why do supernovae explode?
When the pressure drops low enough in a massive star, gravity suddenly takes over and the star collapses in just seconds. This collapse produces the explosion we call a supernova. When stars are especially large, the core collapses into a black hole. Otherwise, the core becomes an ultra-dense neutron star.
What are possible end products of a Super Nova?
Neutron star. One possible end product of a Supernova. When a star much more massive than our sun runs out of fuel, its core collapses, and all of its contents melt into a ball of neutrons more dense than anything else in the universe.
What are the different types of Super Novas?
A supernova is an explosion that occurs with the collapse of a massive star. There are two main types of supernovae: type I supernovae and type II supernovae.
How powerful is a supernova?
The explosion annihilates most of the star as well as anything nearby. While your average supernova generates roughly 10 44 joules of energy — about the same amount that our sun produces over 10 billion years — a super-luminous supernova, like the one discussed here, can explode with up to 50 times more energy.
What happens after a supernova?
What happens to the star after the supernova depends on how big it was to begin with. If the star was only a few times bigger than the Sun, the core will shrink into a tiny neutron star only a few miles across. If the star was much bigger than the Sun, the core will shrink down to a black hole.
