The Lagoon Nebula, or M8, is an enormous cloud of interstellar gas and dust that can be found in the constellation Sagittarius. It is classified as an emission nebula, but it is also referred to as an H II region (a large, relatively low density area of ionized gas where star formation is occurring). This close-up image of the Lagoon Nebula was taken by the Hubble Space Telescope last September.
This dramatic image of the Cone Nebula was taken by the Hubble Space Telescope on April 2, 2002. The Cone Nebula, also known as NGC 2264, is an H II region that can be found in the constellation Monoceros. Its about 2,600 light years away from the Earth.
In fact, the Pacman Nebula is actually creating new stars. This nebula, which is also known as NGC 281, is an H II region that can be found in the the constellation Cassiopeia. NGC 281 got it’s name because it looks like the video game character “Pacman”.
