First Section of Euclid Space Telescope's Map of the Universe Revealed

The Euclid mission has revealed the first part of a 3D map of the universe, showcasing 14 million galaxies and tens of millions of stars with unprecedented detail. 'The Euclid mission, launched in 2023 and run by the European Space Agency (Esa) with contributions from Nasa, sent its first snapshots in November of that year and in May 2024,' reports The Guardian. 'The goal of Euclid is to enable the creation of a 3D map in time and space of the universe, in an attempt to elucidate its evolution and, as a result, shed light on the mysterious phenomena of dark energy and dark matter that together make up 95% of the universe.' From the report: The newly released data is a mosaic of 208 gigapixels and covers 1% of what will be the final map. The completed map is expected to involve six years of observations and will take in a third of the sky, with observations expected to capture billions of galaxies out to 10 billion light years. Images released by Esa highlight the area of the sky covered by the new mosaic, together with the mosaic itself and zoomed-in views within it.

Esa said regions of light blue that can be seen in the mosaic were galactic cirrus clouds that sit between stars in the Milky Way. These wispy clouds, composed of gas and dust, reflect optical light, allowing them to be captured by the mission's super-sensitive visible light camera. Zoom in on the mosaic further and other features can be seen, including the spiral galaxy NGC 2188 and the galaxy cluster Abell 3381. In a view zoomed in 600 times relative to the original mosaic, a distant swirling galaxy is visible in incredible detail.
