Story summary

The European Space Agency’s Euclid telescope released its first full-year dataset, covering about 72 million galaxies—the largest release to date.
The Space Warps project on Zooniverse invites volunteers to review 300,000 AI-selected candidate images, aiming to find over 10,000 new gravitational lenses.
An analysis of just 0.04 % of the data has already revealed 500 previously unseen lenses, which serve as natural scales for measuring galaxy mass, dark matter and cosmic-structure growth.
