ESA’s Euclid Telescope to Reveal First Full-Color Images of the Distant Cosmos

Today, on November 7th, we are on the brink of a remarkable event as we prepare to witness the universe in all its vibrant splendor through the remarkable Euclid telescope, courtesy of the European Space Agency (ESA).

Scientists involved in the Euclid mission have convened in Darmstadt, Germany, to unveil the telescope’s inaugural collection of five breathtaking full-color images capturing the distant cosmos. The world is invited to join in and witness this momentous reveal live on Tuesday at 8:15 a.m. EST (1315 GMT) right here on, with the gracious collaboration of ESA. These images promise to not only be a scientific treasure trove but also a feast for the cosmic enthusiast’s eyes.

Launched in July for a six-year cosmic expedition, Euclid is now stationed approximately 1 million miles (1.6 million kilometers) from Earth, peering into the enigmatic realm of the universe—a position akin to NASA’s powerful James Webb Space Telescope.

Euclid’s mission is to construct a groundbreaking 3D map of the concealed universe by meticulously charting the shapes and distributions of billions of galaxies and star clusters that lie up to 10 billion light-years away. Its primary aim is to unlock the mysteries surrounding elusive dark matter and enigmatic dark energy.

To accomplish this ambitious task, the telescope is equipped to capture a multitude of sharp images encompassing extensive portions of the sky, spanning both visible and infrared wavelengths. This image-rich dataset would be voluminous enough to fill a million DVDs. In its quest to explore the dark universe, Euclid will investigate a cosmic phenomenon known as weak gravitational lensing, which arises from the serendipitous alignment of galaxies or concentrations of matter. This phenomenon allows foreground galaxies to act as colossal magnifying lenses, distorting and, at times, multiplying the light from background sources, creating mesmerizing illusions around lensing galaxies.

Given that visible matter constitutes only a fraction of the total mass within most galaxy clusters, scientists speculate that imperceptible dark matter particles play a pivotal role in this lensing. Therefore, the study of galaxy clusters holds the key to unraveling the behavior and nature of dark matter. To achieve this, Euclid’s images need to be exceptionally sharp to bring the hazy, lensed images surrounding galaxies into sharp focus.

Euclid offered a glimpse of its capabilities in July when it transmitted two images adorned with countless stars and punctuated by distant galaxies. These images were nothing short of captivating.

The forthcoming images are anticipated to be equally enchanting and will serve as a validation of the telescope’s instrument performance, assuring scientists that everything is functioning as planned.

As Roland Vavrek, Euclid’s deputy project scientist, who has been involved with the mission since 2013, aptly stated in a video released on Friday (November 3), “The mission is almost ready to start its six-year collection of data.” The world eagerly awaits the fascinating insights and stunning visuals that Euclid is poised to bring to our understanding of the cosmos.
