The Euclid space telescope is on a mission to map more than one third of the entire sky , observing billions of galaxies over a span of six old age to gather data point about the universe ’s benighted side . In its first big data release , the telescope produced a beautiful mosaic of millions of distant galaxies with different pattern and sizes , give us a glimpse of its power to peer into the cosmos .
On Wednesday , the European Space Agency ( ESA)releasedthe first catalog of datum from the Euclid space telescope , survey an area tantamount to more than 300 time the size of the full Moon . For the first release of the scope ’s six - year survey , Euclid has reconnoiter three plot of land of the sky where it will later make its deep observation of the cosmea .
The telescope appropriate 26 million galaxy in detail , with more than 380,000 galaxies qualify according to their form and distance from Earth . The most remote of the wandflower lies 10.5 billion light years off . scientist from around the world have already begun using the data to meliorate their understanding of the population .

A squad of researchers from the Universities of Oxford , Portsmouth , and Newcastle collaborated with citizen scientists to sift through the datum to identify strong gravitative crystalline lens . Gravitational lenses are when monumental target , such as wandflower , distort spacetime around them , roleplay as a magnifying meth for distant objects by causing the light behind them to twist .
Although gravitational electron lens are hard to spy , the team identify 500 strong lens candidate in the data thus far . To date , there are less than 1,000 fuck strong lens system . “ These lens are already allowing us to learn about our Universe , but this is just the start for Euclid , ” Natalie Lines , Ph.D. student at the University of Portsmouth , said in astatement . “ The full Euclid resume will be a revolution for strong lensing . ”
scientist at the Max Planck Institute for Extraterrestrial Physics ( MPE ) have compiled a catalog using various sky surveys and fuse it with the Euclid data for help distinguish legion galaxy in the gamy - resolution images and quantify their aloofness away from Earth . “ It serves as a introduction for a deeper understanding of these objects , their distribution , and their internal properties , ” Christoph Saulder , a researcher at MPE who go this part of the labor , say in astatement .

The $ 1.4 billion Euclid telescopelaunched on July 1 , 2023on a mission to create the most extensive 3D map of the universe of discourse yet . Euclid is examining the glowering universe — the around 95 % of our cosmos that ’s made up of dark Department of Energy and dark matter — using a seeable clear camera ( VIS ) , a near - infrared camera , and a spectrometer ( NISP ) .
Although the scope is just getting get down on its mission , it has already delivered some impressive snapshots of the dark cosmos . In February , Euclid captured an Einstein Ringin the galaxy NGC 6505 , which is about 590 million short - years from Earth .
The charge ’s first dismission of cosmology data will take place in October 2026 .
