The Trifid Nebula (above), also known as M20, is made up of three different types of cosmic clouds: reddish emission nebulae, blue reflection nebulae and dark nebulae, including the central one divided into three dense bands of dust, from which comes the name of Trifida. The Lagoon Nebula (bottom) is also known as M8 and is also a diffuse nebula. They are between 4,000 and 5,000 light years away from Earth. On the left you can also see the Chinese Dragon Nebula, another star-forming region.
