CAPE CANAVERAL, Fla. (AP) — For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole. The jet power from this relatively close black ...

Among the most extreme objects astronomers study is a class of galaxy that fires a beam of high-energy particles almost directly along the line of sight to Earth. These objects, called blazars, are ...

Astronomers at Caltech captured mind-blowing footage of a supermassive black hole spewing a jet of plasma straight toward Earth. The school’s astrophysicists released a high-resolution video of plasma ...

Powerful jets from supermassive black holes can disturb star-forming gas far beyond a galaxy’s visible edge, leaving a glowing trail hundreds of thousands of light-years long. By keeping this gas hot ...

For more than 30 years, astronomers have been searching for a particular kind of black hole. They knew it should exist somewhere in our galaxy, but they just couldn’t find one. Now, they’ve finally ...

For years, scientists have relied primarily on radio imaging from techniques like very long baseline interferometry (VLBI) to study jets from the active galactic nuclei of supermassive black holes.
