How can a galaxy get destroyed?

Stars will be thrown out of the galaxy, others will be destroyed as they crash into the merging supermassive black holes. And the delicate spiral structure of both galaxies will be destroyed as they become a single, giant, elliptical galaxy.

Is it possible for a galaxy to be destroyed?

No, the supermassive black hole in Sagittarius A* will not eat the galaxy. It's no more than a mote in a swarm of 100 billion smaller motes. Only by collisions and mergers and tidal disruption from other galaxies, as Scott describes. Galaxies are not destroyed by their own supermassive black holes, for example.

Will 2 stars collide in 2022?

According to study from a team of researchers from Calvin College in Grand Rapids, Michigan, a binary star system that will likely merge and explode in 2022. This is an historic find, since it will allow astronomers to witness a stellar merger and explosion for the first time in history.

Will we see a supernova in 2022?

While scientists are confident a supernova will occur in 2022, whether it occurs in our galaxy is a different matter. In any given year, it is an unlikely prospect. On the other hand, one day it may just happen in our galactic neighbourhood. If it does, astronomers say they will be ready.

What can destroy a black hole?

Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.

Can a black hole destroy Earth?

Scientists have debunked this perception. Earth is facing no threat because no black hole is close enough to the solar system for our planet. According to NASA, even if a black hole the same mass as the sun replace the sun, Earth still would not fall in.

Can a black hole eat a black hole?

It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.

What galaxy is 500 million light-years away?

The familiar-looking galaxy — designated TXS 0128+554 — lies around 500 million light-years away from the Earth, in the constellation of Cassiopeia. Analysis of the galaxy's radio wave emissions has revealed that TXS 0128+554 has undergone two bouts of activity in the last century, with a 40-year-gap in between.

Is the sun going to explode?

It is very, very far into the future! Answer 2: The sun is now in the middle of its life cycle, and will explode in about 4-5 billion years In the few hundred million years before the explosion, it will swell up and become a red giant as big as the Earth's orbit. It will therefore swallow the Earth.

What would happen if the sun exploded?

For Earth to be completely safe from a supernova, we'd need to be at least 50 to 100 light-years away! But the good news is that, if the Sun were to explode tomorrow, the resulting shockwave wouldn't be strong enough to destroy the whole Earth. Only the side facing the Sun would boil away instantly.

Is Beetlejuice about to explode?

Called Betelgeuse, it's found in the famous constellation Orion and over millions of years has swelled in size, earning it the title of a "red supergiant." Betelgeuse, over 500 light-years from Earth, will eventually collapse on itself — or perhaps the distant star already has — resulting in a dramatic explosion called ...

Can Andromeda destroy Earth?

'Andromeda has a much bigger and more complex stellar halo than the Milky Way, which indicates that it has cannibalised many more galaxies, possibly larger ones. ' However, Mackey told CNN that this event is unlikely to wreck havoc on our world.
