DETAILS

NGC3923 is an Elliptical galaxy.
This image is presented especially brightened up to bring up very faint light from 3 very distant objects
CXO J115057.8-284401 is a Quasar. They are the most luminous objects in the universe and at distances of over 3 billion light years, are remnants of the early universe. They have large Redshift values and are thought to be a very compact region surrounding a super massive black hole. Light from these has travelled for about half - two thirds the age of our universe which is 13.3 billion years old.
A few other nebulous objects appear in this image but have little or no associated data.
