For the first time in history, scientists managed to observe two dwarf galaxies colliding with each other.
Galaxies colliding with each other and ultimately feeding their inner black hole have been observed many times to date. But scientists Because they are so far from the Milky Way He could not clearly observe this situation in small dwarf galaxies.
With the developing technology, this is now possible. Scientists for the first time two dwarf galaxies colliding with each other observed, both at two different points. Observation holds great clues to understanding the universe.
Dwarf galaxies colliding at two different points in the universe:
- Left: Abell 1758S Right: Abell 133
The first of the binary collisions occurred at a distance of 760 million light years from Earth. Abell 133 observed in the galaxy cluster. The second is 3.2 billion light years away. Abell 1758S found in set. The second collision also included stellar structures that lined up as if they were bridging galaxies.
Observations made through NASA’s Chandra X-ray Observatory are of great importance to the scientific community, as they include dwarf galaxies. Because these galaxies are defined as a window to the early times of the universe.
Caused by the collision of dwarf galaxies a galaxy that contains both a giant black hole coming out. In other words, these four observed dwarf galaxies will be the ancestors of galaxies that will emerge billions of years later.
Therefore, this observed collision may provide new data on how both our own and other galaxies formed.
