Continuing a long line of space telescopes, ESA’s Euclid was launched in 2023 and began its science mission in 2024. It is positioned at the Earth-Sun L2 point. Euclid’s mission is to explore the nature of dark matter and dark energy. It will do so by observing billions of galaxies across more than 1/3 of the sky and up to ten billion light-years away.

Recently the Vera C. Rubin Telescope produced a beautiful image of an ocean of stars. Not to be outdone, in June 2026, the ESA’s Euclid Telescope published a possibly more spectacular image. This latest image is of the bulge at the center of our Milky Way galaxy. Image Credit: ESA/Euclid/Euclid Consortium/NASA, CFHT, image processing by J.-C. Cuillandre and E. Bertin (CEA Paris-Saclay).
