The Euclid Deep Fields – equatorial coordinates

The location of the three fields that will be covered by Euclid's deep survey on a map of the sky, shown in the equatorial coordinate system. The bright, vaguely S-shaped band crossing the image corresponds to the plane of our Milky Way galaxy, where most of its stars reside. The other bright band crossing the image corresponds to the ecliptic – the plane of Earth's orbit around the Sun; the diffuse glow is caused by dust particles in the Solar System.

Euclid is an ESA mission that will image billions of galaxies across the Universe to investigate the past ten billion years of our cosmic history. The largest fraction of the mission's observations will be devoted to a wide survey, covering 15 000 square degrees – more than one third of the sky.

This wide survey is complemented by a deep survey, taking about 10% of the total observing time and repeatedly observing just three patches of the sky: the Euclid Deep Fields, highlighted in yellow in this image.

The Euclid Deep Field North – visible in the upper left portion of the image – is located in the northern sky and spans 10 square degrees. The Euclid Deep Field Fornax, spanning 10 square degrees, and the Euclid Deep Field South, spanning 20 square degrees, are both located in the southern sky and visible in the lower right portion of the image.
