Euclid Telescope invites the public to discover cosmic distortions in new project

Agência Espacial Europeia’s Euclid space telescope has opened the door to an unprecedented collaborative search. Cientistas calls on volunteers from around the world to identify massive galaxies that warp spacetime in never-before-seen images. The Space Warps project, hosted on the Zooniverse platform, combines artificial intelligence with the human ability to recognize subtle visual patterns that machines might miss.

The initiative analyzes around 300,000 images pre-selected by AI algorithms. Esses data is part of the first major official release of information (DR1) of Euclid, scheduled for 2026. Qualquer anyone with internet access can participate, without the need for prior experience in astronomy or astrophysics.

Como gravitational lenses work

Extremely massive Galáxiass act as natural lenses in space. Their gravity bends the light emitted by much more distant objects, creating stunning visual effects. The deflected light forms elongated arcs, multiple images or even complete rings around the central galaxy, phenomena known as Einstein rings.

Esses optical effects reveal information invisible to the eye. Astrônomos can “weigh” galaxies and clusters by measuring how gravity distorts light. The technique exposes the total amount of matter present, including dark matter, which does not emit detectable radiation. Estudos’s strong lensing over time also helps scientists understand the accelerating expansion of the universe and the role of dark energy in that process.

• Imagens show background galaxies distorted into arcs or rings around front galaxies.
• The effect makes it possible to measure the distribution of dark matter inside the lens.
• Dados of Euclid cover an area equivalent to 9,500 times the size of the full Lua.
• Espera will discover more than 10 thousand new strong lenses in this phase of the project.

Resultados impressive in record time

Euclid was launched in July 2023 and has since been capturing large-scale, high-sensitivity images of the sky. By March 2025, researchers had already identified 500 galaxy-galaxy lenses by analyzing just 0.04% of the initial data. Most of these discoveries were completely unknown to the scientific community until then.

The new Space Warps project significantly expands this effort. Artificial intelligence analyzed 72 million galaxies extracted from DR1 data. Voluntários now examine candidates with the highest probability scores. The volume of images for analysis is 30 times greater than previous searches carried out with Euclid data.

The galaxy NGC 6505, located relatively close to Terra, serves as a perfect visual example. Imagens captured by Euclid shows a bright, well-defined ring around it. Esse ring is formed by light from a much more distant galaxy, bent by NGC 6505’s intense gravity.

Participação open and without technical barriers

Access to Space Warps is simple and democratic. Qualquer person with an internet connection can access the project website on the Zooniverse platform and start contributing immediately. The instructions clearly explain what to look for: characteristic distortions around central galaxies. Nenhuma Previous experience in astronomy is required to participate effectively.

Cada clicking and rating done by volunteers helps refine and validate results generated by artificial intelligence. Previous Participantess have already contributed to cataloging hundreds of lenses in early testing of the project. The new large-scale effort seeks to multiply that number significantly. The processed data will directly feed studies into cosmic evolution and the large-scale structure of the universe.

Sinergia between machines and human intelligence

The strategic combination of artificial intelligence and human classification increases overall project efficiency. Computadores processes enormous volumes of data quickly, identifying promising candidates. Porém,Humans detect ambiguous cases and complex patterns with,superior accuracy. The previous project with Euclid demonstrated that this partnership works exceptionally well.

Aprajita Verma, Universidade researcher from Oxford and co-founder of Space Warps, highlighted the transformative potential of the initiative. The larger search area combined with improved algorithms should reveal more than four times the total lenses known from nearly 50 years of astronomical observations. Cientistas hope to use the new lenses to map dark matter in unprecedented detail and refine models of dark energy, which drives the accelerating expansion of the cosmos.

Acesso anticipated cosmic discoveries

Volunteers gain a special privilege: early access to cuts of images that are not yet publicly available. The exceptional quality of photographs captured by Euclid allows you to view fine details in galaxies billions of light years away. Muitos participants report surprise and excitement upon identifying subtle visual distortions that the artificial intelligence had marked as likely.

The project maintains a firm commitment to open science and transparency. Participantes receive contribution certificate for their work. The classifications directly feed the work of researchers from the Euclid consortium, which brings together more than 2,000 scientists from different countries. Euclid continues its six-year mission observing the sky in visible and near-infrared light, measuring both faint lensing and baryonic acoustic oscillations to trace the complete cosmic history.
