"Now we know quasar winds significantly contribute to mass loss in a galaxy, driving out its supply of gas, which is fuel for star formation," Dr. Emanuele Nardini, a research associate at Keele University in England and the lead author of a new paper about the research, said in the statement.
"It's a very nice observation," Dr. Jenny E. Greene, a Princeton University astrophysicist who was not involved in the new research, told National Geographic.
PDS 456 is more than 2 billion light-years from Earth. The measurements were made by NASA's Nuclear Spectroscopic Telescope Array (NuStar) and the European Space Agency's XMM-Newton.
The paper was published Feb. 20, 2015 in the journal Science.
