Scientists have obtained an image of three galaxies approaching each other. It is reported by NASA .
The image was taken by the Hubble Space Observatory. It shows a trio of galaxies in the constellation Bootes under the general name SDSSCGB 10189, separated from each other by 50 thousand light years. years. For comparison, the nearest large Andromeda galaxy is 2.5 million light-years from Earth.
The galaxies gradually converge and eventually collide to form a single large galaxy, distorting each other’s spiral structure through gravitational interaction in the process. Astronomers hope that this image will help to understand the origin of the “brightest cluster galaxies” – especially bright and large galaxies. Most likely, they are formed in the course of such mergers.
Earlier, NASA radar transmitted an image of a 500-meter near-Earth asteroid 2011 AG5.
