APOD 1.5

I was recently looking at the APOD titled The Lagoon Nebula in Stars Dust and Gas. This is a nebula that is so big that it can actually be seen without a telescope near the constellation Sagittarius. This nebula is M8 and spans a distance of 100 light years across. This is cool because M8 was the first nebula that we learned about in our constellation quizzes. In the center of the nebula is a knot of gas which is known as the hourglass nebula.
