1st pair of merging quasars seen at Cosmic Dawn

Artist’s concept of a pair of quasars – bright, active galaxies – merging. Scientists saw these quasars merging only 900 million years after the Big Bang, in a time period known as the Cosmic Dawn. This makes the merging quasars the most distant merging pair known and the first pair astronomers have seen at the Cosmic Dawn. Image via International Gemini Observatory/ NOIRLab/ NSF/ AURA/ M.

Merging quasars at the Cosmic Dawn

Quasars are thought to be extremely bright, active, young galaxies in the distant and early universe.
