The main challenge astronomers face when trying to directly detect black holes is that black holes trap all light. Thus, they cannot be observed directly because no light escapes from them. Instead, astronomers detect black holes by observing their effects on nearby matter or the radiation emitted from the accretion disks surrounding them.
