Last year @ehtelescope released the 1st image of a black hole. Their 2nd image is now out, showing an unprecedented view of quasar 3C 379. 1/n

Quasars have a supermassive black hole pulling in matter at an incredible rate. The energy released by the infalling matter generates powerful beams of high-energy particles that blast away from the black hole at extraordinary speeds.

M87 is ~60 million light years away. But 3C 379 is ~5.3 billion light years away, ~100 times farther. The new EHT result shows amazing detail of a jet produced by a supermassive black hole, detecting the motion of features at velocities of 99.5% of the speed of light.

In @NASA @chandraxray data of 3C379, the separation between the quasar & the bright X-ray source in the jet covers a distance that is about 50,000 times longer than the separation between the two radio sources in the EHT image.

The Chandra & EHT images look similar because both detect emission from regions close to the black hole, both show parts of the same, straight jet. But they are at very different scales.
