Quizplus · Accepted Answer

The Chandra X-Ray Observatory is designed specifically to detect X-rays, which are emitted when matter falls into a black hole. In a binary system, if one of the stars is a black hole, gas from the other star may be accreted onto the black hole, producing X-rays that can be detected by Chandra. The other observatories listed are less suited for this type of observation.
