Using a telescope in Chile, astronomers have captured a high-speed collision between two galaxies located more than 11 billion light-years away, getting a rare direct glimpse into how the universe's most luminous sources of energy, known as quasars, can sculpt their surroundings and influence the evolution of galaxies.
The new findings describe a galactic battle between the galaxy on the right in the image above, which hosts an actively feeding black hole, a quasar, at its center, and its neighbor on the left, which is being bombarded by intense radiation that disrupts its ability to form new stars.
