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.

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.

NASA has discovered a supermassive black hole at the center of galaxy M87, 52 million light-years away from Earth. Estimated to be 2.6 billion times the mass of the Sun, this intriguing black hole ...

Side-by-side simulated images of M87* show the improvement in clarity and resolution from 230 GHz to 345 GHz. These improvements are allowing scientists to measure the size and shape of black ...
