Soft shells and strange star clusters

GC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright centre. Some of these shells are packed close to the centre of the galaxy, while others are flung further out into space. Several wisps of material have been thrown so far that they appear to be almost detached from the galaxy altogether.

Hubble uncovers largest known group of star clusters, clues to dark matter

NASA's Hubble Space Telescope has uncovered the largest known population of globular star clusters, an estimated 160,000, swarming like bees inside the crowded core of the giant grouping of galaxies known as Abell 1689.

These star clusters are on a collision course



NASA's Hubble Space Telescope recently observed two clusters full of massive stars that appear to be in the early stages of merging.
