    Scientists have long theorized that supermassive black holes can wander through space—but catching them in the act has proven difficult.

    Now, researchers at the Center for Astrophysics | Harvard & Smithsonian have identified the clearest case to date of a supermassive black hole in motion. Their results are published today in the Astrophysical Journal.

    Galaxy J0437+2456 is thought to be home to a supermassive, moving black hole.

    Located 230 million light-years away from Earth, the black hole sits at the center of a galaxy named J0437+2456. Its mass is about three million times that of our Sun.

    Using follow-up observations with the Arecibo and Gemini Observatories, the team has now confirmed their initial findings.

    The supermassive black hole is moving with a speed of about 110,000 miles per hour inside the galaxy J0437+2456.

    Zooming-in to the heart of M87 to see a new view of its black hole.

    This zoom video starts with a view of ALMA, a telescope in which ESO is a partner and that is part of the Event Horizon Telescope, and zooms-in on the heart of M87, showing successively more detailed observations

    . At the end of the video, we see the first ever image of a black hole — first released in 2019 — followed by a new image released in 2021: how this supermassive object looks in polarised light.

    This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole.
