Euclid’s 208-Gigapixel glimpse into the Universe - YouTube - ESA - astrophysics/cosmology

The ESA Euclid spacecraft has released the first page of a large cosmic atlas it is photographing,amounting about 1% of the total.The ultimate purpose of the atlas and Euclid spacecraft is to explore the role of dark matter and dark energy in the universe.The first page of the atlas is a huge 208-gigapixel mosaic.The images were collected from 260 observations collected in just two weeks.It was released on 15 OCT 2024 at the International Aeronautical Congress in Milan,Italy by ESA Director General Josef Aschbacher and Director of Science Carole Mundell.*Text by ESA and edited by Andrew Taylor*Cosmology is the study of the origin,evolution and structures of the universe.*Dark matter is about 27% of the universe,while dark energy is about 68% of the universe.

The ESA/NASA Euclid spacecraft promises a wealth of new discoveries because of its unprecedented wide field of view and optical sharpness.It can detect dark matter and dark energy because of these qualities.For example,the large amount of gravitational lensing,a curvature of spacetime,caused by the gravity of massive objects,reveals the substantial presence of dark matter.This was predicted by Einstein's General Theory of Relativity.*Brown dwarf substellar objects,which are failed stars,may account for much of the dark matter in the universe.Brown dwarfs lacked enough mass to initiate thermonuclear fusion.*Even the first five Euclid images have advanced our knowledge of the universe.
