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. Read our excellent blog post by @PeterDEdmonds with @megwatzke at https://chandra.si.edu/blog/node/753
