Six Incredible Photos of Galaxies Colliding - PetaPixel

“The Milky Way typically forms star clusters with masses that are 10 thousand times the mass of our Sun.

Hubble’s ultraviolet and near-infrared observations of these systems have been used to derive star cluster ages, masses, and extinctions and to analyze the star formation rate within these six merging galaxies

The HiPEEC study reveals that the star cluster populations undergo large and rapid variations in their properties, with the most massive clusters formed towards the end of the merger phase.”
