The M87 galaxy is enormous, containing trillions of stars and a supermassive black hole at its center, emitting a 3,000 light-year-long jet of superheated gas. Captured by the Hubble Space Telescope, this jet, described by NASA as “blowtorch-like,” appears to trigger star eruptions. Alec Lessing of Stanford University notes this finding suggests gaps in our understanding of black hole jets. Black holes emit no light, but their accretion disks do, and sometimes material is ejected as jets. The Hubble image shows M87 as a “translucent, fuzzy white cotton ball.”
