The Crescent Nebula (NGC 6888)
=========================

5,000 light-years away, a dying Wolf-Rayet star unleashes violent winds that sculpt glowing shells of gas into this breathtaking crescent. What looks like delicate beauty is actually a cosmic battleground where creation and destruction dance together.

This is why astrophotography transcends science — it reveals the universe’s hidden artistry, one photon at a time. Sometimes the most beautiful art comes from the most violent processes in nature.

📸 Ou4: The Giant Squid Nebula
This elusive nebula glows in blue from oxygen atoms and may lie 2,300 light-years away inside Sh2-129. Powered by a triple star system, its outflows span 50+ light-years. A true deep sky giant.

The Flying Bat & Squid Nebulae
========================

The Flying Bat Nebula, cataloged as Sh2-129, is a large, relatively faint emission nebula located in the constellation Cepheus, about 2,300 light-years from Earth. It lies close to the brighter and more commonly imaged IC 1396 nebula, home of the Elephant’s Trunk Nebula and spans over 2.5 degrees across the sky — about five times the apparent diameter of the full Moon — making it visually impressive but challenging to observe due to its faintness.

Sh2-129 is primarily an H-alpha emission nebula, meaning its reddish glow is produced by ionized hydrogen atoms. Inside Sh2-129 is the remarkable Squid Nebula (Ou4), emitting a striking blue-green light due to doubly ionized oxygen (O-III), forming a very faint, bipolar structure that stretches nearly 50 light-years in length.

HR 8119, the bright star at the center of Ou4, is a hot, massive triple star system and may have launched the outflow that created the Squid Nebula approximately 90,000 years ago. This region also contains a small mixed emission and reflection nebula, vdB 140, further adding to its complexity.

Ou4: The Giant Squid Nebula

This mysterious squid-like cosmic cloud spans nearly three full moons on planet Earth's sky. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's bipolar shape is distinguished here by the telltale blue emission from doubly ionized oxygen atoms.

APOD: 2020 October 7 - Ou4: A Giant Squid in a Flying Bat

https://apod.nasa.gov/apod/ap201007.html

A very faint but very large squid-like nebula is visible in planet Earth's sky -- but inside a still larger bat. The Giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this cosmic scene toward the royal constellation Cepheus.
