Fusion between galaxies is recorded by European astronomical observatory

The Herschel Space Observatory has been able to record images of two galaxies colliding through telescope captures on Earth as well as in space. The collision between the two galaxies causes the emergence of countless stars and in the future, when they calm down, will form a new galaxy.

These images can solve one of the great mysteries of astronomy: the emergence of the universe, which was once populated by reddish and elliptical galaxies made of colliding old stars, such as those now observed. Observing the behavior of these structures now can solve mysteries that have arisen with humanity.

Collision

Current findings suggest that the factor responsible for creating elliptical galaxies has to do with massive mergers. Hai Fu, author of a study that analyzes the new findings, explains that the timing is special, as scientists have the opportunity to observe the adolescent phase of fusion between the two galaxies.

The study's coauthor Asantha Cooray explains that these galaxies are full of new stars amid a lot of dust. Herschel telescope images were able to be captured because the device is able to see infrared light at longer wavelengths.

The colliding galaxies were named HXMM01 and are located 11 billion light years from Earth. These encounters between galaxies cause the emergence of 2, 000 stars a year. The number of stars already present in colliding galaxies is 400 billion. To watch the video showing the collision, click this link.
