Why these Quasar jets appear to travel faster than light

Quasar jets imaged by the Earth Horizon Telescope (EHT) show galactic movements in unprecedented detail. Movements of vast quantities of gas, racing away from Quasar 3C 279 at speeds near the speed of light, reveal signs of a violent past.

In 2019, the The Earth Horizon Telescope (EHT), a network of radio telescopes, released the first-ever image of the region surrounding a black hole. Now, astronomers examining data from this study focused their sights on a different object, a quasar named 3C 279.
