The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958.
Gas and dust likely form around the central black hole, with clouds of charged gas above and below. Astronomers have discovered the largest and oldest mass of water ever detected in the universe â a gigantic, 12-billion-year-old cloud harboring 140 trillion times more water than all of Earth's oceans combined. The cloud of water vapor surrounds a supermassive black hole called a quasar located 12 billion light-years from Earth.
