Hubble has photographed the collision of galaxies.

Telescope Hubble photographed the collision of galaxies. When creating that composite image were used pictures made by Hubble in 2007.

The object, called NGC 2623 captured in the new photo, which is located at a distance of about 250 million light-years from Earth in the constellation Cancer. The unusual shape of clusters due to the fact that it is the result of the collision of spiral galaxies, which include, for example, the Milky Way.

According to scientists, the new data allowed to detect in NGC 2623 some 100 clusters of young stars. The fact that the collision of galaxies contributes to star formation: the gravitational interaction leads to the formation of blobs of gas, which after some time compressed under its own attraction, becoming a star.

NGC 2623 has an active nucleus, which is located in the center of the absorbent cloth supermassive black hole. This object belongs to, according to scientists, one of the merging galaxies.

Studied star cluster belongs to a class of bright infrared galaxies (luminous infrared galaxies — LIRG). In recent years, these galaxies are actively investigated. For example, to collect information about LIRG was organized by a special project GOALS, which was attended by telescopes Hubble, Chandra and Galex.

More recently, astronomers have photographed the biggest clash of galactic clusters. Scientists interested in the system of clusters called MACSJ0717.5 +3745 (or short MACSJ0717), which has a length of 13 million light-years from Earth to a distance of 5.4 billion light years. In this region of space scientists were able to register a triple collision.
