The Lagoon Nebula, also known as Messier 8 or M8, is a breathtaking astronomical wonder located approximately 4,000 light-years away from Earth in the constellation Sagittarius. This emission nebula and H II region is primarily composed of ionized hydrogen gas, making it a massive cloud of interstellar gas and dust. As a stellar nursery, the Lagoon Nebula is the birthplace of numerous young stars, whose intense ultraviolet radiation causes the surrounding hydrogen gas to glow, resulting in the s

Visible light ➡️ infrared! These two Hubble views of the Lagoon Nebula highlight different aspects of this spectacular cosmic object. In visible light, we see mountains of gas and dust surrounding a very hot newborn star. But the near-infrared light reveals an abundance of stars. Most of them are distant, background stars located behind the nebula itself. However, some of these pinpricks of light are young stars within the Lagoon Nebula.
