Homunculus Nebula — nebula, shown live in Cosmoscope, a real-time 3D map of the universe.
Two billowing lobes of dust blasted out of Eta Carinae during an eruption so violent it briefly became the second-brightest star in the sky — a star that survived its own near-death explosion.
Homunculus Nebula 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.
