In the zoom image, which covers only about 10% the area of the full moon, we see spiral and elliptical galaxies, nearby and distant stars, star clusters, and much more. (Credit: ESA)

Euclid’s two instruments, VIS and NISP, have captured their first test images. This important milestone indicates that the telescope and instruments are working well. Euclid was launched on July 1, 2023, and will survey the dark Universe over nearly a third of the full sky, to illuminate the nature of dark energy and dark matter.
