This is the first time that such a large image has allowed us to capture so many Perseus galaxies in such a high level of detail. By mapping the distribution and shapes of these galaxies, cosmologists will be able to find out more about how dark matter shaped the Universe that we see today. ![]() Some of them are so distant that their light has taken 10 billion years to reach us. Many of these faint galaxies were previously unseen. The image shows 1000 galaxies belonging to the Perseus Cluster, and more than 100 000 additional galaxies further away in the background. This incredible snapshot from Euclid is a revolution for astronomy. The first images captured by Euclid are awe-inspiring and remind us of why it is essential that we go to space to learn more about the mysteries of the Universe,” says ESA Director General Josef Aschbacher.Įuclid’s view of the Perseus cluster of galaxies “I wish to congratulate and thank everyone involved with making this ambitious mission a reality, which is a reflection of European excellence and international collaboration. “Our high standards for this telescope paid off: that there is so much detail in these images, is all thanks to a special optical design, perfect manufacturing and assembly of telescope and instruments, and extremely accurate pointing and temperature control,” adds Giuseppe Racca, ESA’s Euclid Project Manager. Now we are ready to observe billions of galaxies, and study their evolution over cosmic time,” says René Laureijs, ESA’s Euclid Project Scientist. ![]() They are even more beautiful and sharp than we could have hoped for, showing us many previously unseen features in well-known areas of the nearby Universe. “We have never seen astronomical images like this before, containing so much detail. “Euclid will make a leap in our understanding of the cosmos as a whole, and these exquisite Euclid images show that the mission is ready to help answer one of the greatest mysteries of modern physics.” Euclid will for the first-time allow cosmologists to study these competing dark mysteries together,” explains ESA Director of Science, Professor Carole Mundell. “Dark matter pulls galaxies together and causes them to spin more rapidly than visible matter alone can account for dark energy is driving the accelerated expansion of the Universe. The images released today showcase this special capacity: from bright stars to faint galaxies, the observations show the entirety of these celestial objects, while remaining extremely sharp, even when zooming in on distant galaxies. What makes Euclid’s view of the cosmos special is its ability to create a remarkably sharp visible and infrared image across a huge part of the sky in just one sitting. By doing this, it will create the largest cosmic 3D map ever made. To reveal the ‘dark’ influence on the visible Universe, over the next six years Euclid will observe the shapes, distances and motions of billions of galaxies out to 10 billion light-years. But we don’t understand what they are because their presence causes only very subtle changes in the appearance and motions of the things we can see. 95% of our cosmos appears to be made of these mysterious ‘dark’ entities. Euclid, our dark Universe detective, has a difficult task: to investigate how dark matter and dark energy have made our Universe look like it does today. ![]()
