3C 273, like many other quasars, is powered by a supermassive black hole at its core, surrounded by swirling gas and dust that emit tremendous amounts of energy as they are pulled into the black ...

Quasars are awe-inspiring – among the brightest objects in the Universe, behind gamma-ray bursts and supernovae. Unlike other ...

The one Hubble studied, designated 3C 273, is one of the closest of these extreme objects to Earth. 3C 273 is incredibly luminous — so much so that, if it were tens of thousands of light-years ...

This supermassive black hole, at the heart of a quasar known as 3C 273, offers a unique view into the complex interplay of galactic forces billions of light-years away. Quasars are luminous ...
