Description

This remarkable emission nebula was discovered by William Herschel in 1784. He classified it as a planetary nebula, simply because of its rounded shape. However, today we use Herschel's term Planetary Nebula. to mean a very specific type of object—a blown off shell of gas from a dying star. Historically this object has been listed as an open star cluster, a nebula, or a star cluster with nebulosity. Later observations have clarified the issue. There is an emission nebula NGC 2467 and two open clusters Haffner 18 and 19 that all belong to the one complex at about 14000 ly from us. With an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas. In the same line of sight there is another group of stars and more nebulosity about 5,500 ly closer to us. So the apparently simple looking 2-dimensional object that we see from earth is in fact very much extended in 3-dimensions.
