An illustration of ESA's Euclid spacecraft. The colors depicted in this illustration are for artistic purposes only.

Euclid will investigate some of the biggest mysteries in the cosmos. Using two instruments, a Near-Infrared Spectrometer and Photometer with NASA-supplied infrared detectors and a visible-light camera, Euclid will work to understand dark matter and dark energy by measuring the expansion of the universe and the distribution of dark matter over cosmic time.

Launched: July 1, 2023
