ESA's Euclid Telescope to Unveil Largest 3D Map of the Universe, Probing Dark Matter and Energy
  • Launched on July 1, 2023, from Cape Canaveral, Florida, the European Space Agency's Euclid telescope is set to create the largest and most accurate 3D map of the universe.

  • The mission aims to investigate the mysteries of dark matter and dark energy, which are believed to constitute about 95% of the universe.

  • Dark matter, which makes up approximately 85% of the universe's total matter, and dark energy, linked to the universe's accelerating expansion, remain undetectable due to their lack of interaction with light.

  • Over the course of its six-year mission, Euclid will catalog 1.5 billion galaxies and provide critical data on their mass and star formation rates.

  • This first image, a 208-gigapixel mosaic, was created from 260 observations taken over two weeks in March and April 2024, covering a 132-square-degree area of the southern sky.

  • The observations will allow scientists to study the evolution of the universe over the past 10 billion years and how dark energy has influenced the distribution of galaxies.

  • The initial mosaic released represents only 1% of the total survey, yet it includes approximately 100 million stars and galaxies.

  • Euclid can survey an area of the sky 100 times larger than that of NASA's James Webb Space Telescope, capturing detailed images of celestial objects.

  • The telescope's 3D mapping will provide precise estimates of galactic masses and cosmic expansion over the last 10 billion years.

  • The Euclid Consortium, comprising over 2,000 scientists from 300 institutions, is responsible for the mission's instruments and data analysis.

  • The initial images showcase intricate features such as spiral galaxies and 'galactic cirrus' clouds, enhancing our understanding of the universe.

  • Currently, 12% of Euclid's mission has been completed, with additional data releases planned for March 2025 and the first year of cosmology data expected in 2026.
