M8 – The Lagoon
Located in the constellation of Sagittarius, in the middle of the Milky Way and in the direction of the galactic center, the M8 nebulae (the Lagoon or the Lagoon) is one of the most beautiful objects in the sky that can be observed.It is located just over 4000 light-years away and spans more than 110 light-years, for 50 light-years wide. It is therefore a nebula of considerable size, whose apparent size in the sky is greater than 3 times that of the Full Moon.
For the most part, it is a nebula in "emission": these are large clouds composed of 90% hydrogen, whose atoms are ionized by the radiation of the newly created stars within them.Real nurseries of stars, the huge clouds of gas condense in multiple places to give birth to as many new stars, whose radiation then illuminates the nebula.  For the Lagoon, the newly created cluster (NGC 6530), about 2 million years old, consists of several hundred young and warm stars.
The nebula is also highly ionized by radiation from the blue supergiant 9 Sag.Many dark (or absorption) nebulae are also present; essentially visible by contrast in front of the emission nebulae. As well as. These areas are so dense and compact that visible light cannot pass through it... on the other hand, thanks to infrared radiation, it is possible to reveal the presence within them of many newly created stars as well as active areas of star formation.
