Euclid mission data release spans more than 900 million galaxies

The release includes 15,000 strong gravitational lens candidates and 1.7 petabytes of data, expanding efforts to map dark matter and dark energy.

  • On Thursday, the European Space Agency released the first major data batch from the Euclid space telescope, covering 13 months of observations across an area equivalent to around 9,500 full Moons.
  • Euclid aims to construct the largest three-dimensional map of the cosmos to investigate dark matter and dark energy, invisible forces accounting for around 95 per cent of the universe.
  • The dataset includes images of more than 900 million galaxies and 60 million quasar candidates. Researchers also identified around 15,000 candidate gravitational lenses, which act as natural magnifying glasses to study dark matter.
  • ESA's Director of Science, Professor Carole Mundell, called the data a 'scientific milestone.' Astronomers describe Euclid as a 'Super-Hubble Space Telescope' with high-resolution imaging across vast sky areas.
  • The mission aims to complete its comprehensive three-dimensional atlas by 2031, observing more than a third of the sky. Future releases will provide initial results on dark energy and dark matter next year.
