The TV series “Star Trek” captured the public’s imagination with the signature phrase, “To boldly go where no one has gone before.” The NASA/ESA Hubble Space Telescope doesn’t “boldly go” deep into space, but it is “boldly peering” deeper into the universe than ever before to explore the warping of space and time and uncover some of the farthest objects ever seen.
Astronomers have uncovered a unique process for how the universe’s largest elliptical galaxies continue making stars long after their peak years of star birth. NASA’s Hubble Space Telescope revealed brilliant knots and chains of hot, blue stars forming along the jets of active black holes found in the centres of giant elliptical galaxies.
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.
