Astronomers monitor a collision between two galaxies that may end with the disappearance of one of them

A similar violent confrontation occurred between our galaxy and Gaia Encelidus about 10 billion years ago, and led to the explosion of stars and the emergence of the Milky Way in its current form.

Using the Hubble Space Telescope, astronomers have observed a "space battle" similar to the battle of David and Goliath, between a huge galaxy and a much smaller galaxy, 220 million light years from Earth.

In a report published by the American magazine "Newsweek", writer Robert Lea says that one of the consequences of the gravitational struggle between the two galaxies is that the group of galaxies "NGC 7752" (NGC 7752) fades and its stars fuse in the Great Spiral Galaxy, a form of Forms of "cosmic disintegration" that is similar to what happened previously in the Milky Way.

Alien galaxies

The Great Spiral Galaxy is known as NGC 7753, and both are located in the constellation of Pegasus. The smaller galaxy appears to be connected to the larger galaxy, so they were classified in the "Atlas of Peculiar Galaxies" compiled by astronomer Halton Arp in 1966, and named it "Arp 86".

NASA predicts that the gravitational battle between the two galaxies will eventually lead to the destruction of the smaller galaxy, spreading its stars, gas and dust throughout the larger galaxy.

The fusion of a small galaxy into a giant galaxy may be similar to what astrophysicists believe happened previously in the Milky Way, which was characterized by a spiral shape similar to the galaxy "NGC 7753", when it was less than 5 billion years old. Currently, the Milky Way may be the result of a fusion with a smaller galaxy, Gaia-Enceladus.

Violent confrontation

According to research published in the journal "Nature Ostronomi Nature Astronomy" that the violent confrontation occurred about 10 billion years ago and led to the explosion of stars after about 4 billion years and the emergence of the Milky Way in its current form. This may not be the last collision in the history of the Milky Way, as it is currently on a collision course with the Andromeda galaxy.

When this collision occurs, NASA says it will reshape the Milky Way, and that the part that contains the Sun and Earth could become a completely different place from what we know today. But, according to scientists, this collision will not occur until after 4 billion years, because the distance between the two galaxies is currently 25 million light years.

According to the author, this type of galactic collision is not a common occurrence in the universe, and researchers believe that it plays an important role in cosmic evolution, as the collision between galaxies leads to the redistribution of gas and dust, which often results in the formation of huge clouds of gas and the formation of stars.
