Stunning photos of six galaxies colliding



As part of the New Year’s celebration, NASA / ESA’s Hubble Space Telescope has released a merger of six galaxies. These rare astronomical phenomena were captured as part of a recent expedition to examine the rate of new stars formation.

At the launch, NASA / ESA explained that these rare merging events showed galaxies drastically altered in the appearance and content of stars.

“These systems are excellent laboratories for tracking cluster formation under extreme physical conditions,” the organization wrote. “Typically, the Milky Way forms a cluster of 10,000 times the mass of stars. week This is not compared to the masses of star clusters forming in colliding galaxies that can reach millions of times the mass of our Sun. ”

The galaxies featured in this week’s Hubble image have a particularly reminiscent name: Medusa’s fusion and are located about 130 million light-years away in the Great Ursa Major (Big Bear).
The system consists of galaxies dubbed IC 694 and NGC 3690, which came close 700 million years ago. As a result of this interaction, the system underwent severe star formation. Over the past fifteen years, six supernovae have surfaced on the outer edge of the galaxy, turning the system into a distinctive supernova factory.

These events give off a lot of light, and even after the collision, as the resulting galactic system fades in a more calm state, the large clusters will continue to shine brightly.

This image shows a strange galaxy NGC 3256.It is about 100 million light-years from Earth and is the result of past galaxies merging, which has resulted in a distorted appearance.As a result, NGC 3256 is an ideal target. Especially in the investigation of starburst from galaxies

These images were selected from 6 out of 59 images that were published in early 2008 and most recently in October 2020.

The NGC 1614 galactic system has a bright center of light and two clear inner spiral arms, which are quite symmetrical.
NGC 6052, located in the constellation Hercules approximately 230 million light years away, is a pair of galaxies that collide.

“Based on the fusion studies of the six galaxies shown here, the Hubble Imaging Vehicle of Extreme Environments and Clusters (HiPEEC) examined how the cluster was affected during A rapidly changing collision that dramatically increases the rate of new star formation in these galaxies, ”wrote NASA / ESA.

“Hubble’s ability has made it possible to fix the ‘nodes’ that form large stars into small clusters. Hubble’s ultraviolet and near-infrared observations were used to determine the age of cluster mass and extinction and to analyze the rate of star formation within the six combined galaxies, the HiPEEC study reveals. It is seen that the constellation has undergone a rapid and large change in its properties, with the largest cluster formed at the end of the integration process. “

NGC 34 is in the constellation The Sea Monster. The outer part of the galaxy appears to be translucent, almost immobilized by the stars and strange little tendons.
