Hickson Compact Group 87 (HCG 87), a small group of galaxies gravitationally interacting and causing bursts of star formation. The image shows a large edge-on spiral galaxy, an elliptical galaxy, and a spiral galaxy. Foreground stars from our own galaxy are also visible. Studying HCG 87 provides insights into galaxy formation and evolution.

Space photo of the week: Record-breaking James Webb telescope image captures 1,678 galaxy groups at once
Astronomers used the James Webb Space Telescope for the largest and deepest sample of galaxy groups, some of which were up to 12 billion light-years away.

The study of galaxy groups, collections of tens to hundreds of galaxies bound together by gravity, reveals how galaxies interact and evolve in less dense environments than galaxy clusters. #GalaxyGroups #GalaxyInteractions #GalaxyEvolution

Galaxy groups and clusters are not static; they are dynamic systems where galaxies are constantly interacting, merging, and influencing each other's evolution. #GalaxyGroups #GalaxyClusters #GalaxyInteractions
