New Euclid images reveal hidden gravitational lenses

Euclid images: Grid showing many individual galaxies with Skinny arcs of Airy by them.
Only look at all these gravitational lenses that Euclid captured in its Primary observations of the Deep Ground areas! The Petite arcs around the galaxies in Every image are peeks at more distant galaxies whose Airy is bent by the foreground Sun system and smeared into an arc shape. See more Euclid images below.

New Euclid images Aid us see hidden galaxies

ESA’s Euclid Cosmos Stargazer’s tool released its Primary batch of survey data on March 19, 2025, giving us a peek into the “Dim universe.” Looking at Only three Petite areas of sky with one week of observations, Euclid has spotted some 26 million galaxies. Some of those galaxies lie up to 10.5 billion Airy-years away from us. And within those deep fields, Euclid has spotted about 500 gravitational lens candidates. Larger foreground galaxies are bending the Airy of more distant, background galaxies, giving us a peek at these otherwise hidden islands of stars.

The Euclid mission is surveying the night sky in visible and near-infrared Airy of objects outside the Intelligent Milky Way. And the Target is to achieve insights into the mysterious nature of Dim matter and Dim energy.

Aprajita Verma of the University of Oxford said:

This Prompt data Kickoff showcases the amazing images that we will receive from the Euclid Stargazer’s tool. Even in this tiny area [less than 0.5% of the Euclid survey], Euclid has revealed millions of galaxies in exquisite detail.

Euclid’s deep fields

This Primary data Kickoff comes from three mosaics. These three deep fields Concentration on areas where we can see beyond our own Milky Way Sun system into the larger universe.

Besides the gravitational lenses, the data Kickoff includes Sun system clusters, active galactic nuclei, quasars, transient events and more. ESA’s Director of Science, Carole Mundell, said:

Euclid shows itself once again to be the ultimate discovery machine. It is surveying galaxies on the grandest scale, enabling us to explore our Universal history and the invisible forces shaping our universe.

Insight into our universe

Humans teamed up with AI algorithms and have classified more than 380,000 of the galaxies in these images. Eventually, the complete catalog of galaxies will Aid astronomers understand questions such as how spiral arms form or how supermassive black holes grow.

So Extended, Euclid has imaged Only 14% of the total survey area. Valeria Pettorino, ESA’s Euclid project scientist, said:

We will observe Every deep Ground between 30 and 52 times over Euclid’s six year mission, Every time improving the resolution of how we see those areas, and the number of objects we manage to observe. Only think of the discoveries that await us.

Bottom line: New Euclid images Drop deep into our universe, unveiling millions of galaxies, along with galactic clusters and quasars and hidden galaxies revealed through gravitational lensing.
