This is Euclid\u2019s Deep Field North. After only one observation, the space telescope has already spotted more than ten million galaxies in this field. It is also very rich in Milky Way stars, as it is close to the Galactic plane. In the coming years, Euclid will make 32 observations of this field to reach its full depth.\u00a0<\/p>\n
Below the centre-left of the image lies the Cat\u2019s Eye Nebula, around 3000 light-years away. Also known as NGC 6543, this nebula is a visual \u2018fossil record\u2019 of the dynamics and late evolution of a dying star. This dying star is shedding its outer colourful shells.\u00a0<\/p>\n
A bit higher to the right of the centre of the image, a large group of galaxies can be spotted, dominated by the large galaxy NGC 6505. This galaxy hosts the first Einstein Ring that Euclid discovered, and is located 590 million light-years away.<\/p>\n
The faint blue structures in the image are dim clouds in between the stars in our own galaxy. They are a mix of gas and dust, also called \u2018galactic cirrus\u2019 because they look like cirrus clouds. Euclid is able to see these clouds with its very sensitive visible light camera because they reflect optical light from the Milky Way.<\/p>\n
Euclid\u2019s Deep Field North has an area of 22.9 square degrees and is located very close to the north ecliptic pole, in the constellation Draco, the dragon. The proximity to the ecliptic pole ensures maximum coverage throughout the year; the exact position was chosen to obtain maximum overlap with one of the deep fields surveyed by NASA’s infrared workhorse, the Spitzer Space Telescope.<\/p>\n

[Image description: On a black background lies a rectangular shape with several stepped notches cut out of its corners, oriented with its longest edges running from bottom left to top right. Contained within the shape are more than ten million galaxies, and stars of various size, brightness and colour. Wispy faint blue cloud-like structures permeate the image, representing gas and dust in between the stars in our own galaxy.]<\/i><\/p>\n<\/p><\/div>\n<\/p><\/div>\n
