‘Castaway’ gamma-ray bursts come from distant early galaxies

Isolated mysterious blasts of intense energy that previously couldn’t be traced back to galactic sources could originate from incredibly dim galaxies located as far away as 10 billion light-years.

An international team of astronomers used some of the most powerful ground and space-based telescopes  —  including the Gemini North telescope in Hawai’i and the Gemini South telescope in Chile  —  to trace the origins of these “castaway” short gamma-ray bursts to incredibly distant galaxies.
