Euclid

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
