- With the Euclid mission, scientists hope to achieve perception about our increasing universe by studying extra about darkish power.
- The mission is mapping the sky in 3D in order that we will higher perceive its construction and composition.
- The primary 1% of this cosmic atlas is now accessible, and it has captured hundreds of thousands of galaxies in unbelievable element.

Euclid mission begins its cosmic atlas
In 2023, the Euclid spacecraft launched from Florida on a mission to be taught why the universe is increasing at an accelerating price. To take action, the wide-angle area telescope is creating probably the most in depth 3D map of the universe but. On October 15, 2024, the Euclid staff launched its first portion – simply 1% – of the cosmic atlas, which covers greater than 500 occasions the realm of the total moon. The 208-gigapixel mosaic offers us a sneak peak of what’s to come back in Euclid’s six-year mission.
The Euclid staff launched the brand new photos on the Worldwide Astronautical Congress in Milan on October 15.
A deep view into area
The mosaic incorporates 260 observations in seen and infrared gentle made between March 25 and April 8 of this 12 months. In simply two weeks, Euclid lined 132 sq. levels of the southern sky, or greater than 500 occasions the realm of the sky lined by a full moon.
The mosaic accounts for 1% of the vast survey Euclid will conduct over six years. Throughout this survey, the telescope observes the shapes, distances and motions of billions of galaxies out to a distance of greater than 10 billion light-years. By doing this, it’ll create the most important 3D cosmic map ever made.
This primary piece of the map already incorporates round 100 million stars and galaxies. Some 14 million of those galaxies may very well be utilized by Euclid to check the hidden affect of darkish power on the universe.
Jason Rhodes is an observational cosmologist at NASA’s Jet Propulsion Laboratory in Southern California. He’s additionally the U.S. science lead for Euclid and principal investigator for NASA’s Euclid darkish power science staff. Rhodes mentioned:
Now we have already seen lovely, high-resolution photos of particular person objects and teams of objects from Euclid. This new picture lastly offers us a style of the enormity of the realm of sky Euclid will cowl, which is able to allow us to take detailed measurements of billions of galaxies.
A better take a look at our universe
Though this patch of area exhibits just one% of Euclid’s complete survey space, the spacecraft’s delicate cameras captured an unbelievable variety of objects in nice element. Enlarging the picture by an element of 600 reveals the intricate construction of a spiral galaxy in galaxy cluster Abell 3381, 470 million light-years away.
JPL’s Mike Seiffert is venture scientist for the NASA contribution to Euclid. Seiffert mentioned:
What actually strikes me about these new photos is the large vary in bodily scale. The photographs seize element from clusters of stars close to a person galaxy to among the largest constructions within the universe. We’re starting to see the primary hints of what the total Euclid information will appear like when it reaches the completion of the prime survey.
Within the new mosaic, we will additionally see clouds of fuel and mud positioned between the celebrities in our personal galaxy. Typically known as galactic cirrus as a result of they appear like cirrus clouds at Earth, Euclid’s visible-light digital camera can see these clouds as a result of they mirror seen gentle from the Milky Method.
Zoom in for unbelievable element
Extra to come back for the cosmic atlas
The mosaic launched right now is style of what’s to come back from Euclid. The mission plans to launch 53 sq. levels of the Euclid survey, together with a preview of the Euclid Deep Discipline areas, in March 2025. The Euclid staff will then launch its first 12 months of cosmology information in 2026.
NASA’s forthcoming Nancy Grace Roman mission can even research darkish power, in methods which are complementary to Euclid. Mission planners will use Euclid’s findings to tell Roman’s darkish power work. Scheduled to launch by Could 2027, Roman will research a smaller part of sky than Euclid however will present higher-resolution photos of hundreds of thousands of galaxies. It would additionally peer deeper into the universe’s previous, offering complementary info. As well as, Roman will survey close by galaxies, discover and examine planets all through our galaxy, research objects on the outskirts of our photo voltaic system and extra.
Backside line: The Euclid mission to survey the universe and assist us perceive the character of darkish power and the increasing universe has simply launched the primary 1% of its cosmic atlas.
