Euclid will image 35 percent of the sky
Euclid will image 35 percent of the sky
The European Euclid space telescope will scan the sky, combining individual measurements to create the largest cosmological survey ever conducted in the visible and near-infrared. This illustration shows the areas that Euclid will cover. The different shades of grey represent the area of the sky that will be covered in just one year during Euclid's total six-year survey. The space telescope will cover over 35 percent of the sky, with a focus on extragalactic sources. This is the largest area Euclid can observe without the overwhelming brightness of the Milky Way (horizontal bright line), its largest satellite galaxy (bright spot in the lower right), and the dust and bright light sources of the Solar System (diagonal bright line) interfering with its observations.
