How does the Hubble Space Telescope take pictures? How long does it take it to take one photo?

The Advanced Camera for Surveys, or ACS, is the primary source of the stunning photos you see online.

In order to capture the various colors at wavelengths of 435, 606, 775, and 850 nm, this camera can take pictures with four different filters. The images are composed of many frames stacked together; each frame takes about 1000 s to acquire in each frequency and is repeated multiple times. Hubble must complete many orbits between the various pictures taken while it is moving and orbiting Earth.

The Ultra-Deep Field, which took 11.3 days to process and involved 112 exposures at 435 and 606 nm and 288 exposures at 775 and 850 nm, for a total exposure time of approximately 1 million seconds, is one of the most detailed images.

The Hubble Space Telescope takes pictures using its advanced imaging instruments, such as cameras and spectrographs. It captures images by pointing its instruments at specific celestial objects or areas of interest and then collecting light over a period of time. The length of time it takes to capture a single photo depends on various factors, including the exposure time and the sensitivity of the instruments being used. Generally, it can take anywhere from a few seconds to several hours to capture a single image, depending on the desired level of detail and the brightness of the target object.
