This week, a team of astronomers working on NASA’s Hubble Space Telescope and the European Space Agency published six images showing the brilliant fusion of galaxies. In fact, when galaxies collide, they tend to look distorted and strange. As reported, the images of the collisions are part of the Hubble Imaging Probe of Extreme Environments and Clusters (HiPEEC) survey, which serves to better understand the formation of stars in wild cosmic places. This is because, in places like this, dense clusters of stars appear that form from merging galaxies. Now, in addition to being especially bright, they leave evidence of long-standing cosmic collisions.
To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.
