An engineering image acquired during testing of one of James Webb Space Telescope’s instruments reveals hundreds of distant galaxies in the deepest ever glimpse into the infrared universe.

The image, released by NASA on Wednesday (July 6), was captured by the James Webb Space Telescope‘s Fine Guidance Sensor (FGS) over an eight-day period in May and encompasses 72 snapshots taken during 32 hours of exposure time. Notably, the FGS, which was built by the Canadian Space Agency, is not a science instrument and instead keeps the observatory pointing properly at its target.
