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

Thanks Ann. Your annotations are very helpful!!

This is a lovely image that screams for annotation!

Oh, and - [url=https://en.wikipedia.org/wiki/The_Treachery_of_Images]This is not a pipe[/url], as French painter Rene Magritte would like to remind us.

[b] Explanation: [/b] [url=https://www.astrobin.com/bim3bg/C/]Dark markings and colorful clouds[/url] 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. [url=http://adsabs.harvard.edu/cgi-bin/bib_query?1919ApJ....49....1B]Cataloged in[/url] the early 20th century by astronomer [url=https://www.pbs.org/seeinginthedark/meet-the-stargazers/in-history.html]E. E. Barnard[/url], the obscuring interstellar dust clouds seen toward the right [url=https://www.saguaroastro.org/the-best-of-barnards-dark-nebulae/]include B59, B72, B77 and B78[/url], part of the Ophiuchus molecular cloud complex a mere 450 light-years away. To the eye their combined shape [url=https://en.wikipedia.org/wiki/The_Treachery_of_Images]suggests a pipe[/url] stem and bowl, and so the dark nebula's popular name is [url=https://apod.nasa.gov/apod/ap200807.html]the Pipe Nebula[/url]. 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 [url=https://www.nasa.gov/feature/goddard/2017/new-hubble-gallery-features-objects-from-popular-not-a-comet-messier-catalog]Charles Messier included[/url] two of them in his catalog of bright clusters and nebulae; M8, the [url=https://apod.nasa.gov/apod/ap210426.html]largest of the triplet[/url], 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 [url=https://apod.nasa.gov/apod/ap210812.html]the Trifid[/url]. M8's popular moniker is [url=https://apod.nasa.gov/apod/ap160909.html]the Lagoon Nebula[/url].
