Beyond imaging the black holes at M87 and Sagittarius A*, the enhanced 870-micrometer capabilities also allow the EHT to observe other active galactic nuclei (AGN) jets with greater precision.

Black hole jets may accelerate and brighten with distance, challenging old models, according to new EHT observations.

This was evident in the case of M87, as presented by RuSen Lu and collaborators in April 2023." Active galactic nuclei, the bright hearts of some galaxies, are powered by supermassive black holes.

On left, this composite simulated image shows how M87* is seen by the Event Horizon Telescope at 86 GHz (red), 230 GHz (green), and 345 GHz (blue). On right, 345 GHz is seen in dark blue ...
