Emission nebula NGC 2174 and its associated open star cluster NGC 2175. They are found in the Orion constellation. A nebula is a cloud of gas and dust in space,many light years across. It is called an emission nebula when the hydrogen gas is ionised,emitting red light. The hydrogen gas is ionised by nearby stars,such as the central bright star that is inside the nebula. A nebula contains materials to form new stars and planets. As well as the open star cluster stars,background stars are also seen | |
