COMMENTS BY THE AUTHORS:
This image of NGC 2024 is a crop of our Barnard 33 image.
The image is rich in detail and a bit surreal so we couldn’t resist this crop. The image still has enough richness, however.
COMMENTS ON THE PHOTO:
The Flame Nebula extends over about 12 light years. Alnitak (Zeta Orionis), the easternmost bright star in Orion’s belt, energises the nebula. The intense ultraviolet radiation from this blue supergiant ionises the hydrogen atoms in the nebula. The ions thus created emit a red glow when they capture a free electron.
Gas and especially dust in front of NGC 2024 absorb the light from the nebula and form the dark ribbon seen in the visible light images.
