Euclid
See ESA - Euclid. Some of the stories are really exciting.
In general, this is a telescope observing visible light (530-920 nm) and near-infrared (920-2020 nm). And yes, the near-infrared is observed with CCD.
Goal: light gravitational lensing dark matter distribution.
By the way, you can only launch 600 of these everyday.
ESA - Euclid’s first images: the dazzling edge of darkness shows a wide Field of View (FoV), compared with JWST. The advantage of a wide FoV is that the distance and location could be meausured more precisely, thus locate dark matter and dark energy more precisely.
