Euclid Telescope's First Data Release Maps 26 Million Galaxies

ESA's groundbreaking mission aims to unravel dark matter and dark energy mysteries with the most detailed 3D map of the universe to date.

Overview

  • The initial dataset includes observations of 26 million galaxies, with 380,000 classified by shape and distance, and 500 strong gravitational lens candidates identified.
  • Euclid's mission will map one-third of the sky, covering 1.5 billion galaxies, to study the universe's large-scale structure and the influence of dark matter and dark energy.
  • Early findings highlight the cosmic web's vast structure, shaped by dark matter and dark energy, and include rare phenomena like double gravitational lenses.
  • Advanced instruments, AI algorithms, and citizen scientists are crucial in processing the telescope's massive data stream, which generates 100 GB daily.
  • This first release represents only 0.4% of the planned survey, with the next major data release scheduled for October 2026.
