NASA celebrates Hubble's 35th anniversary by publishing stunning photos of a nebula that was first captured in 2005.

The team behind this discovery speculates that this gas could eventually become the hot, diffuse gas called the intracluster medium (ICM) that has been seen filling mature galaxy clusters.

Astronomers from Swinburne University in Australia and elsewhere have employed the Keck II telescope to investigate the globular cluster system of an ultra-diffuse galaxy designated NGC5846_UDG1.
