Come and let me tell you about birds and bees – and galaxies. Sometimes two galaxies encounter dramatic consequences, including a star baby boom. NASA and the European Space Agency Hubble Space Telescope have given us six rare ideas of galaxy mergers, and each of them is a winner.
The ESA released images to celebrate the start of 2021. “These systems are excellent laboratories for tracking the formation of star clusters under extremely physical conditions.” The agency said in a statement on Thursday. Star clusters are exactly what they look like: star clusters.
All galaxies show signs of their wild past. The ESA describes the galaxy NGC 3256 as strange and distorted. NGC 3690 is a “supernova factory”, and the image of NGC 6052 shows the two galaxies still colliding.
The HiPEEC (Hubble Imaging Investigation of Extreme Environments and Clusters) survey, which focused images on clusters of stars inside galaxies and what happens when their host systems merge. Collisions promote the formation of new stars, which increases the stellar birth rate.

The ESA stated, “The Milky Way usually groups of masses with stars that are 10,000 times larger than our Sun.” “It does not compare to the mass of star clusters that form in colliding galaxies that can reach millions of times the mass of our Sun.”
HiPEEC researchers have found that large clusters of stars remain very bright in galaxies that have disappeared after the collision. Although the merger can be dramatic for the galaxies involved, viewers on Earth can see spectacular results for Hubble’s stern eyes.
