Andromeda, the killer of galaxies
You can see thousands of stars when the sky is clear and far from the city lights.
There in the northern sky we observe a special celestial body....
Just Andromeda
You can see the Andromeda galaxy with the naked eye, from the side of the North American continent.
It is two and a half million light-years away from the Sun, and contains nearly a trillion stars. It is really gigantic, and we will explain the reason for that huge size. It has just Andromeda, many times the stars of our Milky Way galaxy.
We only see the glowing center of the galaxy, not the entire giant cosmic body
And if we could see it in its full size, we would find the most amazing scene you can see in space
?The Andromeda galaxy is fast approaching.. Why is this happening
Galaxies collide
No body in the universe is stable without me moving, all the bodies of the universe move and rotate.
Moons revolve around planets.
The planets revolve around the stars, and the stars rotate with their planets around the center of the galaxy.
The galaxies revolve around a center of gravity shared by the nearby galaxies
Some of them are in the Local Group, which includes many galaxies.
This unknown center scientists notice its impact on the movement of the galaxies surrounding us.
gravity
Gravity between the clusters of galaxies determines the location of each galaxy in the local group of galaxies relative to each other.
approaching or moving away.
Gravity drives the galaxy as a single entity, and galaxy collisions are common throughout the universe.
It has been observed many times by astronomical observatories.
Scientists suggest that this is the reason why Andromeda is slowly approaching our galaxy.
History of the Andromeda Galaxy
Ancient navigators spotted just Andromeda and thought for a long time that it was a cosmic cloud (nebula), and it was believed that it was located within the borders of our Milky Way galaxy.
Then, its truth was known and observed with astronomical telescopes
After continuous observation of the Andromeda galaxy, scientists have verified several phenomena that indicate that Andromeda has a history of swallowing galaxies and preceded several billion years ago, and the giant Andromeda galaxy swallowed two galaxies smaller than just the Milky Way, and this is evident from the difference in the spread of stars and the direction of that spread in the outer ocean just because of Andromeda .
So to speak, the Andromeda galaxy (a killer of galaxies)
?What happens when galaxies collide
First we compare the structure of the two galaxies:
Both are spiral type
They both have that black hole in the center
Both are surrounded by a halo of gas and dust called the (galactic halo).
Knowing that just Andromeda exceeds the size of the Milky Way galaxy millions of times.
After comparison, we get:
How the collision occurred and its consequences
?You might imagine that when the stars collide, the stars will start hitting each other, right
But it is quite the opposite!!
Many stars will be thrown away into space due to the gravitational effect when the two massive star clusters of the two galaxies approach. When this show begins, we will not be alive, but before that, the life of the sun as a star will end........ so there is no need to worry.....
Watch the video for clarification.
