The main challenge astronomers face when trying to directly detect black holes is that black holes trap all light. This means that light cannot escape from a black hole, making it impossible to observe them directly with conventional optical telescopes. Instead, astronomers often infer the presence of black holes through their gravitational effects on nearby stars and gas, or by detecting the radiation emitted by material accreting onto the black hole.
