signals from black holes

Black holes emit signals primarily through the interaction of matter and energy around their event horizons. When gas and dust spiral into a black hole, they heat up and produce high-energy radiation like X-rays, which we can detect. Sometimes, black holes launch powerful jets of particles traveling close to the speed of light, observable across various wavelengths. These signals help astronomers study black hole properties, such as mass and spin, and understand how they influence their surrounding environment, offering insights into some of the universe's most extreme phenomena.
