Euclid "Dark Universe" Telescope

The huge mosaic released by ESA’s Euclid space telescope on October 15, 2024, accounts for 1% of the wide survey that Euclid will capture over six years. The location and actual size of the mosaic on the Southern Sky is shown in yellow.

A new 208-gigapixel cosmic map, capturing 132 square degrees of the Southern Sky, was unveiled, marking the start of a six-year journey by the Euclid mission to create the largest 3D cosmic map, revealing the universe in unprecedented detail.

The first section of Euclid’s map, a massive 208-gigapixel mosaic, was unveiled at the International Astronautical Congress in Milan, Italy, by ESA’s Director General Josef Aschbacher and Director of Science Carole Mundell.

This mosaic is composed of 260 observations taken between March 25 and April 8, 2024. In just two weeks, Euclid managed to capture 132 square degrees of the Southern Sky with incredible clarity—an area over 500 times larger than the full Moon.               READ MORE...

What the Euclid Space Telescope Sees

The Euclid Space Telescope has revealed the "first page" of the cosmic atlas it is building. The section of the map of the cosmos being built by Euclid was released on Monday (Oct. 15), and it features tens of millions of stars within the Milky Way and around 14 million distant galaxies beyond our own.


The vast cosmic mosaic was constructed from 260 Euclid observations collected between March 25 and April 8, 2024 and contains 208 gigapixels of data. The region charted is around 500 times as wide as the full moon appears in the sky over Earth.

Perhaps most astoundingly, the mosaic accounts for just 1% of the total survey Euclid will conduct over the next six years as it tracks the shapes, distances and movements of galaxies as far as 10 billion light-years away. Not only will this result in the largest 3D map of the cosmos ever created, but the vast scale of this map will help scientists investigate the mysteries of dark matter and dark energy, sometimes collectively known as the "dark universe."     READ MORE...
