Euclid’s mosaic on Gaia and Planck sky map

The huge mosaic released by ESA’s Euclid space telescope on 15 October 2024 accounts for 1% of the wide survey that Euclid will capture over six years. The location and actual size of the mosaic on the Southern Sky is shown in yellow.

This all-sky view is an overlay of ESA Gaia’s star map from its second data release in 2018 and ESA Planck’s dust map from 2014.

[Image description: A dark blue oval image, with a bright band spanning from left to right, from which light blue clouds of smoke appear to be seeping into the rest of the shape. This bright band is interrupted by darker cloudlike structures. In the lower right of the oval there is a small patch marked in bright yellow, which indicates the area of the full mosaic in context of this global map of our Milky Way galaxy.]
