Thank you for supporting this wiki project
Lagoon & Trifid nebulae are one of the most interesting deep sky objects visible in summer night skies, in Sagittarius constellation. They are both hydrogen red emission nebulae, enough bright to be seen with a binocular in dark nights.

Here it is an old film photography of the area, that shows Trifid Nebula (Messier 20) and Lagoon Nebula (Messier 8).

I somewhat agree with Meredith. I voted for humor too beuacse I've loved your work in the past but I would hate to see BlogSalad just become a humor blog. You have too many things to say about too many things.What I liked about BlogSalad as a catch-all is that it reflected you. You're not just a humorist, or just a web designer or just a dad. You're all of that and so much more. I like a blog that reflects the blogger, and BlogSalad, in my opinion, did that.

Good point Jim. The text has been updated to iitacnde that the dark lines in the Trifid Nebula are made up of dark molecular clouds, not dark matter.
