Cosmos Redshift 7 or CR7, a galaxy 12.9 billion light-years away from the Earth, is named after five-time Ballon d'Or winner Cristiano Ronaldo, who is known as CR7.The galaxy discovered in 2015 is considered to be one of the oldest and brightest galaxies in the universe,it was discovered by Dr David Sobral.

Galaxy Cosmos Redshift 7 is reported to be three times brighter than the brightest distant galaxy known up to the time of its discovery and to contain some of the earliest first stars that produced the chemical elements needed for the later formation of planets and life as it is known.

CR7 is a high-redshift Lyman-alpha emitter galaxy. At a redshift z = 6.6, the galaxy is observed as it was about 800 million years after the Big Bang, during the epoch of reionisation. With a light travel time of 12.9 billion years, it is one of the oldest, most distant galaxies known.
