Types of Nebulae | Galaxies, Globular Open Clusters A typical diffuse nebula is a few hundred light-years across (NGC 2264 shown; see also the Horsehead Nebula) Planetary Nebulae Planetary nebulae are shells of gas thrown out by some stars near the end of their lives Our Sun will probably produce a planetary nebula in about 5 billion years

Merope Star | Facts, Information, History Definition The nebula is also named after Merope and sometimes it is referred to as Tempel’s Nebula – in honor of the German astronomer, Wilhelm Tempel, who discovered it in 1859 The diffuse reflection nebula is the brightest around Merope, where it has an apparent magnitude of 13 The rest of the nebula is fainter than magnitude 16
