; NASA, ESA, CXC, C. Ma, H. Ebeling and E. Barrett , et al. and STScI )The European Space Agency's Euclid mission will map the geometry of matter in the universe, specifically in the form of the distribution of galaxies to learn more about the parts of the universe we can't see — dark energy and dark matter.The mission aims to chart 1.5 billion galaxies over the past 10 billion years of cosmic history over its expected six-year lifetime.in its orbit.
Highlighted fields that will be covered by Euclid's wide and deep surveys, on an all-sky map based on data from NASA's Gaia mission. redshift The acceleration behavior is consistent with a sort of"repulsive" energy of the vacuum with constant density or a cosmological constant of theequations, which describe the gravity as a matter versus space-time geometry relationship. Euclid will improve our understanding essentially by measuring whether the dark-energy density is really constant over the last 10 billion years.Dark matter is the predominant form of matter in the universe.
The structural and thermal model of the Euclid spacecraft pictured after completing its thermal qualification tests at Thales Alenia Space's premises in Cannes, France. , Euclid is fairly modest compared to the size and complexity of the James Webb Space Telescope. Euclid's science will be performed by two instruments, and its onboard 3.9 ft specially formulated for the mission. The field of view of VIS is 0.787 degrees by 0.709 degrees .
