The problem with these galaxies is that they are difficult to observe, they are so faint that astronomers have discovered no more than a dozen galaxies in the past decade.
The point may be right there, the secret to the formation of galaxies, and the answer to dark matter.
Now, a team of astronomers decided to use archival data from the Sloan Digital Sky Survey and telescopes at Apache Point Observatory and Las Campanas Observatory to solve the mystery.
They found something spectacular: dwarf galaxy clusters. In fact, 7 galaxy clusters were found, each containing 3 to 5 galaxies that are 10 to 1000 times smaller than the Milky Way.best replica watches uk
These compact galaxy groups were hypothetical until then and had never been observed before.
The discovery may help identify and understand dark matter.
Dwarf galaxies tend to contain more dark matter than larger galaxies, making it a little easier to try to identify mysterious matter in the universe.
Also, because these galaxies are so old, they have little debris such as gas and dust. The presence of gas and dust hinders the search for dark matter.replica swiss watches
then what should we do? A team of astronomers will investigate these galaxies using gamma-ray telescopes.
But why gamma rays? Because dark matter must produce gamma rays as it decays or annihilates in space.replica luxury watches
