A sea of galaxies photographed by Euclid Space Telescope

Extraordinary images of the Euclid Space Telescope have captured 26 million galaxies, some are away as 10.5 billion light years.
Euclid was launched by the European Space Agency (ESA) in July 2023 and sent back its first images in November that year. During the six -year mission, it will give an image about a third of the sky, which will construct the most detailed 3D map of the universe ever created. Once completed, this survey will help illuminate how dark matter and dark energy behave on cosmic parameters.
ESA is now released First mass data from this missionStart with three “deep areas” – areas where binoculars will be more detail than the rest of their survey area. These three spots represent only 63 square degrees of the sky, which is an area equal to the full moon that covers 300 times from the full moon. In the coming years, Euclid will pass these areas between 30 and 52 times, which will ever create a more wide image.
Will be percit The University of Waterloo in Canada states that the current batch of images is less than half a percent of the collecting of the Iklid on the mission, but there is already much more to work with the researchers. He says, “For a lot of individual galaxies and their qualities, there is a lot of science you can, and this is because anyone has not conducted a space-based survey in such a nearest and such optical,” they say. “This is not the same quality of HST (Hubble Space Telescope), but it’s so close, and we are not only indicating and shooting on individual items – we are doing a survey.”

Researchers have already used euclid data to find hundreds of strong gravitational lenses. These events occur when the gravity of an object in the foreground distort light from a distant galaxy, forms an arc shape or even a full ring. Previously, scientists had to hunt them personally and get HST to indicate them and get more images. Now astronomers can find survey data from Euclid and find many at once, which will help collect insight into galaxies and the development of the universe.
Using an AI model, the researchers were able to find and list 500 galaxies with strong gravitational lensing in this first batch of data alone, doubling overall overall. “Statistics are unprecedented,” is called Persian. “Euclid is going to receive this amount of data 200 times at the end.”
The data released so far represents just one week of images from Euclid, but it adds up to 35 terabytes-equal to 200 days of video streaming. The next batch of data, due to release at the end of next year, will be priced at the whole year of images covering 2000 square degrees and requiring more than 2000 terabytes storage space.
It can take a hundred years to manually look at each galaxy, so AI has been used to speed up this process, Mike Valmsle At the University of Toronto. “We can ask new questions in weeks instead of years,” they say.
