What is Black Holes - NASA Science about?
Black holes are dense concentrations of matter with gravity so strong that nothing, not even light, can escape their event horizon. They are detected through their effects on surrounding matter, such as accretion disks and gravitational waves, rather than direct observation. Key facts include the existence of the nearest black hole, Gaia BH1, at 1,500 light-years away, and the largest known black hole, TON 618, which is 66 billion times the mass of the Sun.
