You’d think that
supernovae
– the death throes of massive stars and among the brightest, most powerful explosions in the universe – would be hard to miss. … Based on the number they found in these galaxies, the study confirms that supernovae do indeed occur as frequently as scientists expect them to.
Can a galaxy explode?

Would a supernova destroy the galaxy?
Supernovas are created during the last moments of a star’s life. These gigantic explosions
can wipe out galaxies and the planets inside them
. … These powerful eruptions are called supernovae. They can emit the same energy in a single instant that our sun will generate in over 1 million years.
Can a black hole destroy a whole galaxy?
Is it possible for a black hole to “eat” an entire galaxy? No.
There is no way a black hole would eat an entire galaxy
. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
What can destroy a galaxy?
Black holes
might kill entire galaxies with blazing energy,dooming embryonic stars before they can get born and condemning the remainingstars to a slow death, scientists have found.
Will we see a supernova in 2022?
This is exciting space news and worth sharing with more sky watch enthusiasts. In 2022—only a few years from now—an odd type of exploding star called
a red nova will appear in our skies in 2022
. This will be the first naked eye nova in decades.
Could a supernova destroy a planet?
If our sun exploded as a supernova, the resulting shock wave
probably wouldn’t destroy the whole Earth
, but the side of Earth facing the sun would boil away. Scientists estimate that the planet as a whole would increase in temperature to roughly 15 times hotter than our normal sun’s surface.
What is the scariest thing in the universe?
The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun, or 20 times the size of the solar system. Whereas the outer planets in our solar system orbit once in 250 years, this much more massive object spins once every three months.
What is the most powerful thing in the universe?
Quasars
inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
Where do things go in a black hole?
It is thought that the matter that goes into a black hole gets
crushed into a tiny point at the center called a “singularity”
. That’s the only place that matter is, so if you were to fall into a black hole you wouldn’t hit a surface as you would with a normal star. Once it’s there, it’s there.
Is Goku a Buster universe?
Super Saiyan God Goku is NOT a universe buster but
he is universal

Is it possible to destroy the universe?
We could destroy the universe
. … Einstein’s general theory of relativity suggests that concentrating this kind of energy in a volume smaller than an atom might distort space and time enough to tear a hole in the fabric of the universe. This “mini black hole” could rapidly expand to engulf the entire cosmos.
How much energy does it take to destroy a galaxy?
Our Sun, for reference, has a mass of 2*10
30
kg, so he’d need the equivalent of
280 Suns
to destroy an entire (small) galaxy.
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.
Will there be a supernova in 2021?
For the first time, astronomers have found convincing evidence for a new type of supernova – a new sort of stellar explosion – powered by electron capture. They announced their discovery in
late June 2021
. … Astronomers designate this supernova SN 2018zd. It lies in a remote galaxy, NGC 2146, 21 million light-years away.
What is the youngest star?
If proven, the newly discovered neutron star will be the youngest one known by humanity, beating the current youngest supernova remnant is
Cassiopeia A
, which is 330 years old that can be found 11,000 light-years away from Earth and can be found within our galaxy.
