What to know about Astrophysics

Researchers from the University of Oxford and Curtin University have measured the instantaneous power of jets from the black hole Cygnus X-1. Using 18 years of radio imaging, the team determined the jets possess the power of 10,000 suns and move at half the speed of light.

What happened

Black hole jets measured in real time, revealing 10,000-sun power Andrew Zinin Lead Editor For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

Why it matters

The jet power from this relatively close black hole-star system is equivalent to 10,000 suns, an international research team reported Thursday.

Common ground

They also tracked the jet speed: roughly 355 million mph (540 million kph)—half the speed of light.
