APOD: The Central Milky Way from Lagoon to... (2021 Oct 01)

Image The Central Milky Way from Lagoon to Pipe

Explanation: Dark markings and colorful clouds inhabit this stellar landscape. The deep and expansive view spans more than 30 full moons across crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E. Barnard, the obscuring interstellar dust clouds seen toward the right include B59, B72, B77 and B78, part of the Ophiuchus molecular cloud complex a mere 450 light-years away. To the eye their combined shape suggests a pipe stem and bowl, and so the dark nebula's popular name is the Pipe Nebula. Three bright nebulae gathered on the left are stellar nurseries some 5,000 light-years distant toward the constellation Sagittarius. In the 18th century astronomer Charles Messier included two of them in his catalog of bright clusters and nebulae; M8, the largest of the triplet, and colorful M20 just above. The third prominent emission region includes NGC 6559 at the far left. Itself divided by obscuring dust lanes, M20 is also known as the Trifid. M8's popular moniker is the Lagoon Nebula.

This is a lovely image that screams for annotation!

Central Milky Way from Lagoon to Pipe annotated Gabriel Rodrigues Santos.png

1) Sharpless 2-34.

2) Young open cluster M21.

3) The Trifid Nebula.

4) The Lagoon Nebula.

5) NGC 6559. I couldn't find a bigger picture, sorry!

6) O-type star HD 162978 surrounded by nebula Sharpless 2-22.

7) NGC 6520.

8) Globular clusters NGC 6528 and NGC 6522.

9) Sagittarius Teapot spout star Gamma-2 Sagittarius?

10) Cluster NGC 6451. The cluster is at upper right.

11) The Sh 2-15 to Sh 2-20 complex of HII regions located in the Sgr OB5 association in the Sagittarius arm. Sharpless 2-18 belongs to this complex of nebulas.

12) The Pipe Nebula!

13) The Snake Nebula. Check out the Dark Horse Nebula while you are on that Wikipedia page, because the Snake Nebula and the Pipe Nebula are both parts of the Dark Horse Nebula.

14) Theta Ophiuchi, one of my favorite stars in this part of the sky because it is lovely and blue! :D

Oh, and - This is not a pipe, as French painter Rene Magritte would like to remind us.

I love photos like this on APOD! :D I like the Lagoon very much; and
the Trifid! The pipe is also neat!
Nicely done Gabriel Rodrigues Santos
