NASA Space Telescopes Spot an Early Universe Surprise: A Mature Galaxy Cluster FriendsofNASA.org: A new discovery captures the cosmic moment when a galaxy cluster—among the largest structures in the universe—started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will force astronomers to rethink when and how the first galaxy cluster in the
