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.[1]
Cosmos Redshift 7 (also known as COSMOS Redshift 7, Galaxy Cosmos Redshift 7, Galaxy CR7 or CR7) is a high-redshift Lyman-alpha emitter galaxy. At a redshift z = 6.6,[1] the galaxy is observed as it was about 800 million years after the Big Bang, during the epoch of reionisation.[1] With a light travel time of 12.9 billion years, it is one of the oldest, most distant galaxies known.
CR7 shows some of the expected signatures of Population III stars i.e. the first generation of stars produced during early galaxy formation.[1][2][3][4][5] These signatures were detected in a bright pocket of blue stars; the rest of the galaxy contains redder Population II stars.[3] However, recent studies show no evidence for population III stars in CR7.[6]
