Sagittarius Dwarf Irregular — galaxy, shown live in Cosmoscope, a real-time 3D map of the universe.
A remote, pristine scrap of a galaxy — its stars are so poor in heavy elements that it offers a glimpse of the early, unenriched universe.
Sagittarius Dwarf Irregular is placed at its true position on the sky and at its real measured distance, not as a flat backdrop. Fly out from the Sun in the live 3D view and watch it change from a point of light into structure as you approach, with the scale bar showing just how far out you have travelled.
