DescriptionEuclid begins its dark Universe survey ESA25479326.jpg
English: Euclid will scan across the night sky, combining separate measurements to form the largest cosmological survey ever conducted in the visible and near-infrared. This animation shows the areas it will cover. The different shades of grey/blue depict the area of the sky covered during Euclid’s six-year survey. Euclid will scan over one third of the sky, focusing on the extragalactic sources. This is the largest area it can cover while avoiding the overpowering brightness of the Milky Way galaxy (horizontal bright line), its largest satellite galaxy (bright spot bottom right) and the dust and sources in the plane of our own Solar System (diagonal bright line).

Different shades of grey and blue depict the area of the sky covered during Euclid’s six-year survey. An horizontal bright line in the oval shows the Milky Way band, and a diagonal line shows dust and other sources in our own Solar System. An artist impression of the Euclid spacecraft is visible in the lower right corner.]
