  Expansion of the Universe

Image: The galaxies are not moving away from each other but the Universe is growing. The sizes of the galaxies do not change but the distance between the galaxies increases.

note: Euclid is the space mission selected by ESA (scheduled for 2023) which could provide answers concerning the true nature of the Universe. Euclid will probe the history of the expansion of the Universe and that of the formation of cosmic structures. The objective is to measure the distribution of matter in the universe and the way in which this distribution has evolved since the Big Bang.
The name of the mission was chosen in honor of Euclid (300 BC), a Greek mathematician considered to be the father of geometry.
