The intense electromagnetic environment near black holes can accelerate particles to near-light speeds, forming jets that extend from the poles. In supermassive black holes, these jets can expel material beyond the galaxy. A recent study of galaxy M87 revealed an unusually high frequency of nova explosions near one of its jets, with no clear mechanism or similar activity in the opposite jet. Further observations are needed to confirm and explain this phenomenon. M87’s central black hole has active jets, and Hubble Telescope observations showed novas clustering around one jet, which is puzzling given the stable nature of nova cycles. Researchers are revisiting this with Hubble.
