Space is just as mysterious as the ocean's depths. We know very little of the vast expanse of either and as we go farther and deeper, we discover more amazing things than what our imaginations can fathom.
What is a quasar? To put it simply, it is a massive object of hot gas and dust being sucked in by a black hole that emits powerful amounts of energy.
A quasar can produce more energy than the entire galaxy in which it resides. Although the basic mechanism that powers a quasar is known, the anatomy of the supermassive black hole and its surroundings is not well understood. Where does the gas that feeds the black hole come from? And what effect does the resulting intense radiation have on the environment around the black hole? The findings of the GRAVITY Collaboration provide a way to answer these fundamental questions.
