Image of the Month for January 2021: The Horsehead and Flame Nebulas
The Horsehead Nebula or Barnard 33 is a small dark nebula, whose fame arises from two things - fortuitously lying in front of a 'curtain' of ionised hydrogen gas and a remarkable resemblance to a horse's head. This image also shows the bright double star Alnitak (note the smaller companion star just left of the main star), and the bright Flame nebula (NGC 2024 or Sh2-277). Again the Flame nebula is the result of bright hydrogen behind a dark dust cloud. Smaller areas of blue reflection nebula where the dusty nebulas scatter starlight are also visible in the image. This image is a composite of three monochrome images filtered for the light of hydrogen alpha, sulphur ii and oxygen iii mapped in that order as red, green blue and then colour balanced.
