Hubble team breaks cosmic distance record

4 March 2016 Astronomy Now

By pushing the NASA/ESA Hubble Space Telescope to its limits, astronomers have shattered the cosmic distance record by measuring the distance to the most remote galaxy ever seen in the universe. The galaxy, named GN-z11, has a redshift of 11.1, which corresponds to 400 million years after the Big Bang when the universe was only three percent of its current age.


A new record: Keck Observatory measures most distant galaxy

6 August 2015 Astronomy Now

EGSY8p7 is the most distant confirmed galaxy whose spectrum obtained with the W. M. Keck Observatory places it at a redshift of 8.68, at a time when the universe was less than 600 million years old. Hydrogen emission from EGSY8p7 may indicate it is the first known example of an early generation of young galaxies emitting unusually strong radiation.
