Scientists who have studied the cosmos with the space telescope Hubble found that some of the Milky Way started the clash between the four smaller galaxies. Group dwarf galaxies, which is known as number 31 in the Hickson catalog, are in 166 millions of years from the Milky Way.
The researchers found the age of the cosmos some clusters of stars in these galaxies, which corresponds to 10 billion years. These data indicate that the galactic group 31 is old enough, despite the fact that its galaxies started to interact with each other long ago - a hundred million years ago.
Scientists were able to observe the active star formation in the group, using the camera on the Hubble. In addition, they were able to examine the cluster of bright stars and determine their age, as well as volumes of gas in them. Using infrared observations, scientists have found that the age of the brightest star clusters is not more than 10 million years.
According to scientists, the galaxies must spend the entire cold gas and unite in less than one billion years. The result of unification will be an isolated elliptical galaxy of low mass.
