- Nóta "The word ""nebula"" is Latin for mist or cloud, and the term ""planetary nebula"" is a misnomer that originated in the 1780s with astronomer William Herschel because when viewed through his telescope, these objects resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and has not been changed.Reference: 'Planetary nebula'. Wikipedia, https://en.wikipedia.org/wiki/Planetary_nebula [18.5.2017]"
