When to Use Planetary Nebula 3D Explorer - Best Sessions and Limits
Open the Planetary Nebula 3D Explorer when you need the slow glowing shell around a white dwarf - Ring Nebula teaching case ~2,600 ly, shell speed ~20-30 km/s - and skip it when you need a supernova shock shell or a full stellar timeline alone.
A five-minute classroom demo
A five-minute classroom demo starts when you open Planetary Nebula 3D Explorer, scrub age forward in kyr, and pause so students see the green shell grow while the white-dwarf core marker stays fixed at the center.
Shell-speed literacy in Planetary Nebula 3D Explorer
Shell-speed literacy in Planetary Nebula 3D Explorer stays readable when you keep the facts panel open for ~20-30 km/s and contrast it against the ~1,500 km/s supernova-remnant figure while toggling the outer halo.
Sessions Planetary Nebula 3D Explorer does not fit
Sessions Planetary Nebula 3D Explorer does not fit are photoionization physics, real HST filament mapping, or supernova shock modeling. Use Supernova Remnant 3D for fast shock shells or Star Lifecycle 3D for the full evolutionary timeline. Walk the controls in the Planetary Nebula 3D Explorer step-by-step guide.
