ACS stands for the Advanced Camera for Surveys. The ACS is three cameras in one: a wide-field camera, a high-resolution camera, and a solar-blind camera, which is sensitive to ultraviolet light. The camera also has a coronagraph, which blocks out the glare of quasars and stars so astronomers can study fainter objects in the same vicinity. The camera’s vision ranges from ultraviolet to visible light.
