A black hole tore apart a star and brought together astronomers from around the world

It was an event not seen in over a decade: a sudden burst of energy launched from the center of a distant galaxy, bright enough to be visible 8.5 billion light-years away. . With a burst of light equivalent to more than 1,000 trillion suns, the flash was first detected by the Zwicky Transient Facility, …

A bright flash detected in February was a black hole jet pointed directly at Earth

A bright flash detected in February was a black hole jet pointed directly at Earth

Drawing: Carl Knox – OzGrav, ARC Center of Excellence for Gravitational Wave Discovery, Swinburne University of Technology On February 11, astronomers saw a distant flash of light that seemed to come from a source as bright as a quadrillion suns. They alerted other scientists to the event, and several telescopes quickly swung around to focus …

NASA’s IXPE Helps Solve Black Hole Jet Mystery

Astrophysicists solve mystery of 40-year-old black hole jet with NASA’s IXPE

This illustration shows NASA’s IXPE spacecraft, right, observing blazar Markarian 501, left. A blazar is a black hole surrounded by a disk of gas and dust with a bright jet of high-energy particles pointed at Earth. The inset illustration shows high energy particles in the jet (blue).

We now know why black hole jets produce high-energy radiation

We now know why black hole jets produce high-energy radiation

Enlarge / The jets of material ejected around black holes can be enormous. Active galactic nuclei, powered by the supermassive black holes they contain, are the brightest objects in the Universe. The light comes from jets of matter projected at a speed close to light by the environment around the black hole. In most cases, …
