Lagoon Nebula
The Lagoon Nebula (also known as Messier Object 8 (M8) and NGC 6523) is a giant interstellar cloud and H II region, in the constellation Sagittarius.

The Lagoon Nebula is a giant stellar nursery that has given birth to hundreds of new stars. Yet the nebula still contains vast clouds of gas and dust, which glow red in this image from Kitt Peak National Observatory, that could form even more stars.
The Lagoon Nebula is a giant interstellar cloud awash with star-forming pods, seen in the image as dark patches that permeate the nebula.
The Lagoon Nebula is five degrees west of lambda Sgr and one degree north. M17 (NGC 6618), the "Swan Nebula" or the "Omega Nebula", and occasionally known as the "Horseshoe Nebula".
The Lagoon Nebula, or Messier 8 (NGC 6523), is a large interstellar cloud, 110 by 50 light-years in dimension, identified as an emission nebula. It lies near [7301] lambda Sagittarii and is about 4,100 light-years distant.

Next to the Lagoon Nebula on our sky (but closer to us in space) is the Trifid Nebula, so-called because of the dust lanes that trisect the H II region behind them.
This is the Lagoon Nebula, 4,500 light years away. It is much larger and brighter than its neighbor the Trifid Nebula and even visible with the naked eye on a dark night.

The image of the Lagoon Nebula (M8) is also taken by the Hubble Space Telescope. It lies approximately 5,200 light-years away, and was originally discovered in 1747.

The famous Lagoon Nebula, M8, is probably the best of the diffuse nebula and one of the finest in the sky. As it is of 6th mag the naked eye can see it in a dark night.
About 1 1/3 degrees from the Lagoon Nebula we find the Trifid Nebula. This is also a dusty nebula which is also known as NGC 6514, or more simply, M20. It is about 60% dimmer than M8, and spans half a degree across the sky.

The Lagoon Nebula, M8, is just below center, while the open clusters M7 and M6 lie to the left of the Scorpion's lower tail. The center of the Galaxy lies down and to the right of M8.
The exact centre of the Galaxy is believed to be marked by a radio-emitting source that astronomers call Sagittarius A. There are many notable objects in Sagittarius, including the Lagoon Nebula and the Trifid Nebula, ...
energy distributions such that most of the energy is emitted at infrared wavelengths; (3) absence of discrete features in low-dispersion spectra; and (4) strong and rapidly varying polarization at visual and radio wavelengths. [H76]

Again, if you're a deep-sky aficionado, M 8 (Lagoon nebula) nearly aligns with this southern solstice point. At a southern major lunar standstill, the Moon brushes up close to the star Alnasl.
The small reddish spot toward left center is the Lagoon Nebula, M 8, which lies below Polis and just to the left of the Winter Solstice. Down and to the left of the Little Milk Dipper lies the semi-circle of Corona Australis, the Southern Crown.
