M84 — galaxy, shown live in Cosmoscope, a real-time 3D map of the universe.
One of the bright anchors of Markarian’s Chain — a smooth elliptical whose core hides a billion-Sun black hole betrayed by two small jets of glowing plasma.
M84 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.
