It was released the first Universe map, made by the observations of space telescope Euclid, it has 208 gigapixels.

The mosaic contains 260 observations made between 25 March and 8 April 2024. In just two weeks, Euclid covered 132 square degrees of the Southern Sky in pristine detail, more than 500 times the area of the full Moon.
This mosaic accounts for 1% of the wide survey that Euclid will capture over six years. During this survey, the telescope observes the shapes, distances and motions of billions of galaxies out to 10 billion light-years. By doing this, it will create the largest cosmic 3D map ever made.
This first piece of the map already contains around 100 million sources: stars in our Milky Way and galaxies beyond. Some 14 million of these galaxies could be used to study the hidden influence of dark matter and dark energy on the Universe.
“This stunning image is the first piece of a map that in six years will reveal more than one third of the sky. This is just 1% of the map, and yet it is full of a variety of sources that will help scientists discover new ways to describe the Universe,” says Valeria Pettorino, Euclid Project Scientist at ESA.
The spacecraft’s sensitive cameras captured an incredible number of objects in great detail. Zooming very deep into the mosaic, we can still clearly see the intricate structure of a spiral galaxy.
A special feature visible in the mosaic are dim clouds in between the stars in our own galaxy, they appear in light blue against the black background of space. They are a mix of gas and dust, also called “galactic cirrus” because they look like cirrus clouds. Euclid is able to see these clouds with its super sensitive visible light camera because they reflect optical light from the Milky Way. The clouds also shine in far-infrared light, as seen by ESA’s Planck mission.
Since the mission started its routine science observations in February, 12% of the survey has been completed. The release of 53 square degrees of the survey, including a preview the Euclid Deep Field areas, is planned for March 2025. The mission’s first year of cosmology data will be released to the community in 2026.
