It's so rare to see this one north up. :D

Also a challenge for Ann, try finding it in [url=https://www.astrobin.com/372584/]this image[/url].

Haven't figured out how to draw words on pictures, so I'll have to describe:

The bright round cloud at far left surrounds hot runaway star Zeta Ophiuchi. The fainter cloud with "condensations" at upper left contains the Blue Horse. The small round condensation inside the larger faint cloud at upper left is an emission nebula surrounding Pi Sco. The largish blob of emission nebulosity to the left of Pi Sco is an emission nebula surrounding Delta Sco. There is an apparent "gap" in the emission nebulosity to the left of Delta Sco, and in the middle of this gap, we can see Beta Sco. And below and slightly to the left of Beta Sco we can see Nu Sco, which is the blue eye of the Blue Horse.

Blue horses are nice. Nice APOD! :D

[b] Explanation: [/b] Do you see the horse's head? What you are seeing is not the famous [url=https://apod.nasa.gov/apod/ap121021.html]Horsehead nebula[/url] toward [url=https://apod.nasa.gov/apod/ap120909.html]Orion[/url] but rather a fainter nebula that only takes on a familiar form with deeper imaging. The main part of the [url=http://www.galaxlux.com/IC%204592%20The%20Blue%20Horse%20Nebula.htm]here imaged[/url] [url=https://apod.nasa.gov/apod/ap120129.html]molecular cloud[/url] complex is a [url=http://en.wikipedia.org/wiki/Reflection_nebula]reflection nebula[/url] cataloged as [url=http://en.wikipedia.org/wiki/IC_4592]IC 4592[/url]. Reflection nebulas are actually made up of very fine [url=https://apod.nasa.gov/apod/ap030706.html]dust[/url] that normally appears dark but can look quite blue when reflecting the [url=https://science.nasa.gov/ems/09_visiblelight]light[/url] of energetic nearby stars. In this case, the source of much of the reflected light is a star at the [url=http://www.youtube.com/watch?v=tw0VJ1K93PM]eye[/url] of the [url=http://3.bp.blogspot.com/-DYPBo1QCnls/UBAUokUjOFI/AAAAAAAAAck/gSVevljIUUc/s640/funnyface.jpg]horse[/url]. That star is part of [url=http://en.wikipedia.org/wiki/Nu_Scorpii]Nu Scorpii[/url], one of the brighter star systems toward the constellation of the Scorpion ([url=https://en.wikipedia.org/wiki/Scorpius]Scorpius[/url]). A second [url=https://apod.nasa.gov/apod/reflection_nebulae.html] reflection nebula[/url] dubbed [url=http://wise.ssl.berkeley.edu/gallery_ic4601.html]IC 4601[/url] is visible surrounding two stars to the right of the image center.
