Astronomy Picture of the Day - The Horsehead Nebula
NASA ^ | 25 Nov, 2024 | Image Credit & Copyright: Alex Lin (Chilescope)

Explanation: One of the most identifiable nebulas in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s. The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left. Streams of gas leaving the nebula are funneled by a strong magnetic field. Bright spots in the Horsehead Nebula's base are young stars just in the process of forming. Light takes about 1,500 years to reach us from the Horsehead Nebula. The featured image was taken from the Chilescope Observatory in the mountains of Chile.

Now that I am retired, I would love to learn how to put a bright red MAGA right down the horse’s neck. Even the Cosmos recognizes good news.

Any report that brings up Sigma Ori. is all right by me. It’s a cool star system.
