Supernova Facts
- Have you ever thought what happens when a star dies, how it happens, what it causes, what effect on the galaxy?

- What is a supernova?
The powerful and luminous stellar explosion is called a supernova or when a star dies it explodes this explosion is called a supernova.
- How does a star die?
At first, we should understand that every star has a nuclear fuel. When a nuclear fuel
get run the star dies.
- What happens after a supernova?
Whatever left after a supernova explosion is a neutron star when the core of the st collapsed or with sufficient mass, the black hole is created.
- The most powerful supernova ever seen?
ASASSN-15lh is the most powerful superluminous supernova ever seen, a star in a billion of the galaxy of light-year which is 600 billion times brighter than sun and 20 times brighter than all the star in milky way galaxy.
- What is bigger than Supernova?
Superluminous supernova or hypernova is bigger than a supernova which is 5 10 50 time more energy than a supernova.

- Do all-star go supernova?
All-stars will reach core collapse but with some star which has sufficient mass than star collapse directly into a black hole without producing a visible supernova.

- What is the acceleration of supernova?
Scientists have captured the blast from a supernova 10,000 light-years away in a cosmic speed trap, clocking the shockwave from the dead star's explosive end at speeds of nearly 8 miles per second.
- How big is a neutron star?
A neutron star has a mass of about 1.4 times the mass of the sun, but is not much bigger than a small city, about 15 km in radius. A teaspoon of neutron star material would weigh about 10 million tons.
- Can a supernova kill a planet?
Yes, but when stars at least 7 to 10 times the mass of our sun go supernova, the blast swallows any inner planets, those orbiting out to several times the distance between Earth and the sun.
