Astronomers at Steward Observatory have discovered a massive protocluster around a super-luminous quasar.
Such objects, detected at high redshifts, could provide important information about the early phases of the Universe.Astronomers have discovered a new massive protocluster around the…
A collapsor plasma jet can slow a black hole’s rotation until it almost stops.
When black holes appear as stars collapse, they momentarily eject jets of material that literally slow their rotation until it stops completely. Most black holes…
A galaxy with stars that are too old has been discovered in a young universe
For seven years, a team of astronomers searched for rare galaxies in the early universe to estimate their age. They finally succeeded. Data was collected…
