Look at an unusual globular cluster, where there are stars of different ages

Ruprecht 106 is a young globular cluster located 69.1 thousand light years from Earth in the constellation Centaur.

Astronomers used the telescope to better understand the cluster's structure, since it is unlike most similar objects.

Typically stars form in globular clustersin approximately the same place, at the same time, as well as a similar chemical composition of the stars. And in Ruprecht 106 there are stars whose chemical composition is unexpectedly different. A very small number of clusters have the same anomaly, and scientists cannot yet understand why this happens.

Hubble took this picture with its most versatile tool, the camera (ACS).

Earlier, Hubble showed a photo of two galaxies that are “crashing” into each other. This is an object called Arp 40.
