Most Distant Star Ever Seen: Supernova Explodes 5 Billion Years Ago
9 de Septiembre de 1988: The most distant, individual star ever recorded was detected with a telescope at the ESO La Silla observatory on August 9, 1988. The object is an exploding star, a supernova, and is situated in an inconspicuous galaxy, itself a member of a distant cluster of galaxies. Additional observations indicate that the cluster, known as AC118, is at a distance of about 5 billion light-years (1 billion = 1000 million). Thus this supernova explosion occurred 5 billion years ago, or about the time when the Sun and the planets were born. Ever since then, the light emitted by this event has been travelling towards us, only arriving here now. It is the most distant supernova (ESO8802) observed so far.
