The very bright star on the left of the image is Alnitak, the eastern
most (left most) star in Orion's belt. Like everything else in this
picture (and almost everything in the constellation of Orion), it is 1500
light years away. There are 4 separate nebula in this picture.
The Flame Nebula, also known as NGC 2024, lies below Alnitak. IC 432
is the blue reflection nebula to the right of the flame, and IC 434 is the
red emission nebula to the right of Alnitak. The most famous part of
this image is the Horsehead Nebula, or Barnard 33, and it is a dark dust
cloud which lies between us and IC434. The Horsehead Nebula is
nearly impossible to see in even the largest amateur telescopes under the
best conditions. It is so faint, in fact, that it was only
discovered and cataloged in the 1910s by E. E. Barnard, although it turns
out it was visible in a photographic plate taken in the year
1900. |
