space telescope Hubble from NASA and the European Space Agency captured a “dangerous dance” image of two merged galaxies. They are two sets of spiral constellations located a hundred million light-years from Earth: NGC 5953 and the NGC 5954. In the aftermath of the merger, scientists gave it a common name: Arp 91.
Arp 91 is an example of galactic interaction. The circulating image shows that NGC 5953 (bottom) is “pulling” NGC 5954. “The gravitational force of the two galaxies makes them interact”Stressing that such interaction phenomena are “common”, as well as an “important part of galactic evolution,” NASA said.
Andromeda and the Milky Way
In addition, NASA has shown that collisions between spiral galaxies can lead to the formation of elliptical galaxies. It is estimated that the merger will occur in about 4.5 billion years. According to the images, the Milky Way will affect a neighboring galaxy, Andromeda, with a diameter of 220,000 years and an age of 150,000 light-years.
The moment the merger takes place, there will be a planetary collapse. Since it is in the initial stage, it will likely take several hundred million years to complete. The moment of impact will be given by the gravity of large galaxies, which will lead to the elliptical galaxy after colliding with recien will occur, according to astronomers, in about a hundred million years.
Hubble was launched into orbit in April 1990 and is approximately 600 km above sea level. It takes just over an hour and a half to travel around the circumference of the Earth.
