The European Space Agency's Euclid space telescope has released its first major data set, offering new insights into dark matter and the universe's expansion. This initial data comprises one week's worth of deep field images from three points in space, representing just a small fraction (0.4%) of the area Euclid is designed to capture. Despite this limited scope, Euclid has already identified 26 million galaxies, each potentially containing millions of stars and billions of planets.

Euclid's data release includes mosaics covering 63 square degrees of the sky, revealing galaxy clusters, active galactic nuclei, and transient phenomena. Significantly, it provides the first classification survey of over 380,000 galaxies and identifies 500 gravitational lens candidates. One rare phenomenon captured in the new batch of data is double gravitational lensing, where light from two distant galaxies passes through the same galaxy, causing a double lensing effect. These early observations promise significant advancements in our understanding of cosmology and astrophysics, particularly regarding dark matter and dark energy.
