This image is of three beautiful nebulae in a narrow band. Above, right of the center is the spectacular region, called Messier 8 (also known as the Lagoon Nebula).

M8 (another one of its designations) was discovered by Charles Messier in the 18th century. He also discovered the region on the left; M20 (most commonly known as the Trifid nebula).

Along with its beautiful, this emission nebula is huge; encompassing an area of space about 30 to 100 light-years across.

Finally (pictured in the bottom right), we have another emission nebula; classified as NGC 6559.

Together, this collection of stellar nurseries can all be found approximately 5,000 light-years from Earth in the constellation of Sagittarius. They provide quite a view against the cosmic canvas that is our home galaxy, the Milky Way.

Narrow emission lines can be seen in this false-colored composite , which mapped trace amounts of hydrogen, sulfur and oxygen atoms, using various filters. The green, red and blue color scheme was made popular by the Hubble Space Telescope, but for the ground-based telescopes, narrow-band filters help to minimize the light pollution problem, which often prohibits us from getting a good glimpse at deep-space objects.
