What happened? The European Space Agency’s Euclid Mission released the first batch of survey data this week, with a glimpse of hundreds of thousands of galaxies in diverse sizes and sizes, as well as transient events such as many galaxy clusters, active galactic nuclei, and supernova and gamma-ray burst. The data covers a sufficient area of the sky in three mosaics, reflecting the ability of the mission to detect the mass organization of galaxies within the cosmic web.
“Euclid once again shows to be the final search machine. It is surveying the galaxies on the most grand scale, which enabled us to detect our cosmic history and invisible forces shaped by our universe,” said Professor Karol Mundel, director of ESA science, Professor Karol Mundel. He said that this data release unlocks a treasure of information for scientists to deal with some most complicated questions in modern science.
In only one week of observations, Euclid has identified 26 million galaxies, located far away from 10.5 billion light-year. These deep areas also have a small population of bright quasters, some of which are visible from even more distance. In the coming years, Euclid will see these areas again again, capture many more distant galaxies and will make these areas really ‘deep’ by the end of the mission in 2030.
The initial glimpse of 63 square degrees of the sky previews the scale of the Grand Cosmic Atlas of Euclid, which will eventually cover one-third -14,000 square degrees-high quality expansion of the entire sky.
“We will inspect each deep area between 30 to 52 times on the six -year mission of Euclid,” ESA’s ESA’s Euclid Project Scientist Valerino said, every time we see the areas, and correction to see the things we see. ” “Just think about the discoveries that are waiting for us.”
Galaxy
Euclid’s high-resolution visible imaging system (VIS) and near-ending equipment (NISP) are important for measuring the size and distance of the galaxy, respectively, providing insight into the mass organization of galaxies within the cosmic web. It is necessary to understand dark matter and dark energy, including about 95 percent of the universe.
Euclid is expected to capture images of over 1.5 billion galaxies, producing about 100 GB of data daily. The combination of AI algorithms and civil science is important when analyzing this huge dataset. “We are in an important moment how we deal with large -scale surveys in astronomy,” said Mike Valmsley, scientist at Euclid Consortium. “AI is a fundamental and essential part of our process to completely exploit the huge dataset of Euclid.”
Euclid strong gravitational lens
Euclid is also a powerful tool for studying gravitational lensing, a phenomenon where light is distorted by the light foreground case from distant galaxies. Mission has already identified 500 strong lens candidates, most of which were unknown earlier. The aim of Euclid aims to catch thousands and such lenses on its mission by combining AI models with civil science and expert vet.
The first universe of the mission will be released in October 2026.
