New Hubble discovery.

The NASA Goddard space flight center shares a new Hubble discovery. The image above shows a massive galaxy cluster glowing brightly in the darkness. The cluster is named of PLCK G308.3-20.2.

Galaxy clusters can contain thousands of galaxies all held together by the glue of gravity. These massive formations typically contain dozens of galaxy clusters and groups and span hundreds of millions of light-years.

"One of the most interesting features of galaxy clusters is the stuff that permeates the space between the constituent galaxies: the intracluster medium (ICM)," said NASA in an announcement.

High temperatures are created in these spaces by smaller structures forming within the cluster. This results in the ICM being made up of plasma -- ordinary matter in a superheated state. Most luminous matter in the cluster resides in the ICM, which is very luminous in X-rays. However, the majority of the mass in a galaxy cluster exists in the form of non-luminous dark matter. Unlike plasma, dark matter is not made from ordinary matter such as protons, neutrons and electrons. It is a hypothesized substance thought to make up 80% of the universe's mass, yet it has never been directly observed.

This image was taken by Hubble's Advanced Camera for Surveys and Wide Field Camera 3 as part of an observing program called RELICS (Reionization Lensing Cluster Survey). RELICS imaged 41 massive galaxy clusters with the aim of finding the brightest distant galaxies for the forthcoming James Webb Space Telescope to study.
