Emission Nebula Lab
Interactive 3D-style canvas simulation: Emission Nebula Lab.
Strömgren radius4.1 pc
Ionized gas78%
Dominant emissionHα + [O III]
A hot young star photoionizes its natal cloud: the ionization front sweeps outward to a Strömgren radius set by the UV photon rate. Higher UV pushes deeper [O III] teal toward the core while the shell keeps glowing in Hα.
