This very wide celestial field in Ursa Major presents a dense and varied collection of extragalactic and galactic structures. Galaxies The region is dominated by the M81 Group, a gravitationally interacting assembly of galaxies located approximately 12 million light-years away. More precisely, measurements using Cepheid variable stars observed by the Hubble Space Telescope place the group at a…
