The Euclid Mission of the European Space Agency (ESA) released its first series of survey data on Wednesday (March 19), including a preview of its deep fields that reveal hundreds of thousands of galaxies in various shapes and sizes.
Why is it great?
This image, which is only one zoomed area of three released mosaics, represents a data release of Euclid spacecraft from ESA with countless milking clusters, active galactic cores and transient phenomena, as well as the first classification study of more than 380,000 star sets and 500 virginity candidates.
“With the release of the first data from Euclid’s Sky Survey, we unlock a wealth of information for scientists to dive and tackle some of the most intriguing questions in modern science,” said Carole Mundell, director of Science of ESA, in a statement. “With this, ESA provides its dedication to make scientific progress for coming generations possible.”
What does it show?
This is from Euclid’s Deep Field South, a first glimpse of 63 square degrees of heaven, the equivalent area of more than 300 times the full moon. For comparison, when completed, Euclid’s Atlas will be a third of the entire air-14,000 square degrees decks in this high-quality detail.
In this specific view, galaxies can be identified by their elongated shape or spiral arms. Some are advanced, while one prominent spiral galaxy at the lower center is face-on. At the far right, between the middle and the top of the image, are galaxies that are interaction with each other.
Galaxy clusters are also seen in the vicinity of the lower center, where functions that are lubricated in arches represent the gravity lenses.
This image shows an area of Euclid’s Deep field South that has been zoomed in 70 times compared to a general mosaic. Huge Galaxy clusters are visible in this image, including one in the middle that nearly 6 billion light years have been removed. | Credit: ESA/Euclid/Euclid Consortium/NASA, Image processing by J.C.

What can astronomers learn from this?
The Euclid spacecraft has already seen 26 million galaxies with the furthest to 10.5 billion light years. Because of his survey, astronomers will learn more about Galaxy forms and star formation, in addition to other topics of study.
“We will each observe deep field between 30 and 52 times during the six -year mission of Euclid, every time the solution is improved of how we see those areas, and the number of objects we manage to observe. Just think of the discoveries that are waiting for us,” said Valeria Pettorino, Euclid Project Scient of Euclid.
