Scientists find the largest observed black hole to date


The team spotted the black hole using data from theVery Large Telescopearray. The wealth of extra data from the Chile observatory helped them map the structure of Holm 15A in unprecedented detail, helping them run simulations to explain the galaxy’s formation and its unusually faint center. Simply speaking, the black hole is so powerful and large (its radius is about 790AU) that it has either swallowed up the closest stars or tossed them toward the galaxy’s edge.

This isn’t necessarily largest black hole detected. That distinction goes to the quasar TON 618 — indirect studies suggest its black hole could be 66 billion times the Sun’s mass. It’s still gigantic, though, and it’s about four to nine times than astronomers expected. The discovery could significantly expand humanity’s understanding of the scale of the universe, not to mention fundamentals like galaxy formation.
