What is a black hole and how did we discover them?

WebBy using a spectroscope, the Hubble Space Telescope has the ability to clock the speed of this gas as it swirls around the entrance to the hole. The speed with which the gas swirls is considered the black hole's signature. By knowing the speed of the gas, the mass of the black hole can be calculated. WebBlack holes don't radiate light, and an object that falls inside a black hole doesn't emit light either, so detecting them can be challenging. Just as with neutron stars, if a black hole is in a binary and it strips gas from its companion, we can detect X-rays from the resulting accretion disk (see "Observing Neutron Stars" ).
