On the cosmic mosaic of space telescope Euclid, you can zoom in until you weigh an ounce

The Euclid space telescope is mapping the universe in unprecedented detail, aiming to photograph over 1.5 billion galaxies to study dark matter and dark energy. Launched in 2023, it will take six years to complete its mission, creating a 3D cosmic mosaic. Euclid's wide field of view allows it to capture vast areas of the sky quickly, significantly surpassing previous telescopes like Hubble. The telescope utilizes gravitational lensing to reveal hidden galaxies and understand the distribution of dark matter. This mission involves a collaboration of around 2,000 scientists, including theorists who are actively shaping its objectives. The data collected will enable extensive statistical analysis, potentially leading to new insights into the universe's structure and the nature of dark energy.
