"The discovery is shedding new light – literally – on the universe.
...The LOFAR telescope works by pick up traces, or "jets," of ancient radiation produced when galaxies merge. These jets can extend over millions of light years.
"LOFAR has a remarkable sensitivity and that allows us to see that these jets are present in all of the most massive galaxies, which means that their black holes never stop eating," said Philip Best, a professor of extragalactic astrophysics at the University of Edinburgh.
Black holes have a gravitational pull so strong that no matter can escape them. The new observations will allow scientists to compare black holes over time to see how they develop.
...The known Universe just got a lot bigger
...Using information from NASA's Hubble space telescope, scientists believe there are more than 100 billion galaxies in the universe. However, many may be too old and too far away to be observed using traditional detection techniques.
