Journey to The Lagoon Nebula in Sagittarius | European Southern Observatory

This zoom takes the viewer from a wide view of the central parts of the Milky Way deep into a detailed picture of the Messier 8 star formation region—the Lagoon Nebula—from the VLT Survey Telescope at ESO's Paranal Observatory in Chile. This giant cloud of gas and dust is creating intensely bright young stars, and is home to young stellar clusters. Commonly known as the Lagoon Nebula, Messier 8 (M8) was discovered in 1654 by the Italian astronomer Giovanni Battista Hodierna. He, like Charles Messier, sought to catalog nebulous objects in the night sky so they would not be mistaken for comets. This star-forming cloud of interstellar gas is located in the constellation Sagittarius, and its apparent magnitude of 6 makes it faintly visible to the unaided eye in dark skies, and easily seen with binoculars or small telescopes. The best time to observe M8 is during August.

Located 5,200 light-years from Earth, M8 is home to its own star cluster: NGC 6530 (not visible in the image above). The massive stars embedded within the nebula give off enormous amounts of ultraviolet radiation, ionizing the gas and causing it to shine.
