According to NASA, astronomers have long suspected dwarf galaxies have previously merged to form the larger galaxies visible today, but no modern technology can observe these mergers because they are so far away from Earth that they can hardly be seen.



The Chandra X-ray Observatory of NASA has reportedly found evidence of enormous black holes on a collision path in distant dwarf galaxies for the first time.

Dwarf galaxies, according to NASA, are composed of stars with a combined mass of less than 3 billion suns, or about 20 times that of the Milky Way.



According to NASA, astronomers have long suspected dwarf galaxies have previously merged to form the larger galaxies visible today, but no modern technology can observe these mergers because they are so far away from Earth that they can hardly be seen.

One pair of black holes, according to NASA, have been discovered in the galaxy cluster Abell 133, which is 760 million light-years from Earth. The region is known as Mirabilis and contains two dwarf galaxies that appear to be merging in their final phases. Chandra's X-ray data is pink and CFHT's optical data is blue in the above picture.



In Abell 1758S, a galaxy cluster about 3.2 billion light-years from Earth, the other pair of black holes were found. Chandra X-ray data is also shown in pink on the right side of the picture above, while CFHT optical data is shown in blue. The merging dwarf galaxies Elstir (bottom) and Vinteuil (top) were given these names by the scholars in honour of fictional characters from Marcel Proust's

According to NASA, the merger of the black holes and dwarf galaxies may now shed light on the Milky Way's history.

According to scientists, the majority of galaxies started out as dwarf or other tiny galaxies and grew over the course of billions of years as a result of mergers.
