A sea of galaxies that are photographed by the EUCLID -ROmelescope

Extraordinary images from the EUCLID -Rum Telescope have caught 26 million galaxies, some as far away as 10.5 billion light years.
Euclid was launched by the European Space Agency (ESA) in July 2023 and feels back its first pictures in November of that year. During a six-year mission, it will imagine one-third of the sky that builds the most detailed 3D card of the cosmos ever created. When completed, this study will help illuminate how dark fabric and dark energy behave on cosmic scales.
ESA has long released the first scale data from this mission, starting with three “deep fields” area, where the telescope will look more detailed than in the rest of its study area. These spots take only 63 square meters of sky, an area similar to that covered by full moon 300 times. In the coming years, Euclid will pass over these regions between 30 and 52 times and build an ever -detailed image.
Will Percival at the University of Waterloo in Canada says the current batch of images is less than half a percent of what Euclid will gather over the mission, but there is already planty for researchers to work with. “For many individual galaxies and their characteristics, there is so much science you can do, and that’s because no one has done a space -based study in the near infrared and the optical like this one before,” he says. “It’s not as the same quality as HST [the Hubble Space Telescope]But it is very close and we do not just shoot and shoot at individual objects – we do a study.

Researchers have already used the euklid data to find hanging by strong gravitational leader. These phenomena are formed when the gravity of an objex in the foreground distorts light from a distant galaxy, creating a bow mold or even a full ring. Previously, scientists had to chase these down individually and get HST to point them and gather more images. Now astronomers can search for the study data from Euclid and find many at once, which will help gather insight into the development of galaxies and the universe.
Using an AI model, scientists were able to find and catalog 500 galaxies with strong gravitational lens in this first batch of data alone, which doubled the total number so far. “The statistics are phenomenal,” says Percival. “Euclid will get 200 times this love for data in the end.”
The released data previously represents a single week’s images from Euclid, but they add approx. 35 Terabbytes equivalent of 200 days with high quality streaming. The next batch of data to be released late in next year will be a full year’s value of images covering 2000 square degrees and requires more than 2000 Terabbytes storage space.
Looking at each Galaxy could manually take over a hunting year, so AI has been used to massively speed up the process, says Mike Walmsley at the University of Toronto. “We can ask new questions for weeks rather than years,” he says.
