A new citizen science project launched The European Space Agency (ESA) and the Euclid Consortium, He cooperated The Institute of Astrophysics of the Canary Islands (IAC) and the Zooniverse platform, Will allow Volunteers around the world can identify the shapes of millions of galaxies in images taken by ESA’s Euclid space telescope.
The initiative aims to train Artificial Intelligence Deep Neural Network According to the IAC, this enabled the creation of the largest catalogue of galaxy morphologies to date.

“The world will be able to see its quality in November 2023 and May 2024 when the first images from the European Space Agency’s Euclid mission are released, showing sources ranging from nearby nebulae to distant galaxy clusters. This is just the beginning; Euclid will continue to take images of hundreds of thousands of distant galaxies in its mission to map the universe.”, which details the IAC.
Over the next six years, the mission expects to send Starting in 2025, 100 GB of daily data from Earth and Euclid will be used to publish the first data catalog for the scientific community. In the meantime, though, any volunteer on the Galaxy Zoo project can view the telescope’s unreleased images.

The first dataset, containing tens of thousands of galaxies selected from more than 800,000 images, is now available on the platform, awaiting classification.
“If you participate in the project, you can be the first person to see Euclid’s latest images. Not only that, you may also be the first human to see the Milky Way in the image.”, pointing out Mark Huertas & Co., Researcher at the Institute of Astrophysics of the Canary Islands (IAC), responsible for the scientific development of satellites of the Euclid Consortium to characterize the structure of galaxies.
This image shows 1,000 galaxies belonging to the Perseus star cluster, with more than 100,000 galaxies farther away in the background. Each has hundreds of billions of stars.
Many of these faint galaxies have never been seen before, and some are so far away that they cannot be observed. Its light took 10 billion years to reach Earth.

galaxy.
IAC said the classifications are not only useful for their immediate scientific potential, but can also serve as training sets for artificial intelligence (AI) algorithms.
“If humans don’t teach the AI what to look for, the algorithm has a hard time classifying galaxies. But together, humans and AI can accurately identify an unlimited number of galaxies.”Huertas warned.

In Zooniverse, the team developed an AI algorithm called ZooBot that examines Euclidean images and labels the “simplest” ones, many of which already exist in previous galaxy surveys. ZooBot is unsure of the galaxy’s classification, it will display it to the user to get its classification, This helps the algorithm learn more.
IAC recalled that Euclid was launched in July 2023 and began routine science observations on February 14, 2024, aiming to reveal the hidden influence of dark matter and energy in the visible universe.
So, over the course of six years, Euclid will observe the shapes, distances and motions of billions of galaxies, up to 10 billion light-years away.
