“Astronomers are studying the immense energy emitted by the quasar located billions of light-years away.”

“In essence the galaxy is eclipsing the quasar, but paradoxically its gravitational lens effect brightens the light received from the latter.”

“The moving cosmic string would have acted as an additional gravitational lens, affecting both quasar images simultaneously.”

“I read up on interstellar objects and astrophysics and studied quasars, pulsars and supernovas, but my main focus was black holes.”

“When the light we see today left the farthermost quasars, the earth and the solar system had not yet been born.”

“But eventually, having developed techniques to mask the light, astrophysicists were able to detect fuzz surrounding some of the dimmer quasars.”
