Is it possible to see a star explode?

Is it possible to see a star explode?

In a first for astronomy, researchers were able to see in real time the death by explosion of a giant red star using ground-based telescopes. They saw the star, located 120 million light-years away from Earth in the NGC 5731 galaxy, self-destruct in a dramatic event and collapse in a type-2 supernova.

Has supernova been seen?

Supernovas are usually detected only after they explode, but this time the star was spotted 130 days before its end. For the first time, astronomers have observed the final days and death throes of a red supergiant star before its final collapse and massive explosion into a supernova.

Will we see a supernova explosion in 2022?

Yes, it is true that somewhere there is likely to be a supernova during 2022. It is likely to be in another galaxy. Supernova that are visible to the naked eye on Earth occur, on average, once every 200–400 years. The most recent one was supernova 1987a.

Why is it possible to see a supernova explosion but not hear it?

Light does not require a medium to travel through but sound requires a medium, so it cannot be transmitted through space. That is why we are able to see the supernova explosions but cannot hear them.

Will I see a supernova in my lifetime?

Unfortunately, supernovae visible to the naked eye are rare. One occurs in our galaxy every few hundred years, so there is no guarantee you will ever see one in our galaxy in your lifetime. In 1987, a supernova called 1987A was visible in a nearby galaxy called the Large Magellanic Cloud.

Would you hear a supernova in space?

Sound itself can only be transmitted through a medium and so in space we cannot hear a supernova. However since a supernova is a giant explosion triggered by the final death throes of a massive star, if we could hear it, we would hear an incredibly loud blast.

When was the last red nova?

In January 2015, a luminous red nova was observed in the Andromeda Galaxy. On February 10, 2015, a luminous red nova, known as M101 OT2015-1 was discovered in the Pinwheel Galaxy.

Can you see a star supernova explosion in the night sky?

A STAR has gone into supernova and there’s a chance you’ll be able to see the explosion in the night sky. An amateur astronomer detected the death of the star near the constellation of Cassiopeia. According to the Astronomers Telegram, the supernova was first detected on March 18 by amateur astronomer Yuji Nakamura who viewed it from Japan.

Can a supernova leave behind the densest objects in the universe?

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. Astronomers and careful observers saw the supernova in the year 1054.

What is a supernova?

A supernova is a powerful and bright stellar explosion It occurs during the last evolutionary stages of a massive star, or when a white dwarf goes into runaway nuclear fusion The original object collapses into either a neutron star or black hole, or is completely destroyed

How can I see a star explode?

If you live in a country in the Northern Hemisphere, like the US or UK, you should be able to spot the exploding star with a small telescope. You’ll need to locate the Cassiopeia constellation in the northern sky.
