"A planetary nebula, often abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding glowing shell of ionized gas ejected from old red giant stars late in their lives. Lupus: Stingray Nebula: Hen 3-1357 1989 18 (approx.) These objects represent the final stage before a planetary nebula.

Mostly the well known, with beautiful color and considerably bright, perhaps containing an obvious hole, or clearly a central star. List of planetary nebulae. Planetary Nebula: in order of Right Ascension: Planetary Nebula: in the constellations: The descriptions : This Top 40 list gives you the easiest and most beautiful of Planetary Nebula, quickly found in your telescope. Jump to navigation Jump to search. A protoplanetary nebula usually glows with the light from its parent star. 16.5 Grus: Retina Nebula: IC 4406: 1888–1907 2.0 (approx.) Many distances are estimates (denoted by the approx. These nebulae are formed during the last stages of a star's life when a red giant star casts of its outer layers in a process which leads to the star becoming a white dwarf. suffix), as true distances are difficult to infer for planetary nebulae.
Others are overabundant in nitrogen; the most luminous ones, observed in external galaxies, are conspicuous examples. The planetary nebulas shown here are NGC 6543, also known as the Cat's Eye, NGC 7662, NGC 7009 and NGC 6826. Please see main article, Planetary nebulae , for more details on distance estimates.
Mostly the well known, with beautiful color and considerably bright, perhaps containing an … These outer layers of gas expand into space, forming a nebula which is often the shape of a ring or bubble. Contents. Some are carbon-rich, with twice as much carbon as oxygen, while there is more oxygen than carbon in the Sun. The following is an incomplete list of known planetary ... Spare-Tyre Nebula IC 5148: 1894 3 (approx.) It is located about 2° south and slightly west of the 4th-magnitude star Mu (μ) Hydrae.

Please see main article, Planetary nebulae , for more details on distance estimates. It's sometimes called the Ghost of Jupiter because it's similar in size and color to the planet Jupiter.

This gallery shows four planetary nebulas from the first systematic survey of such objects in the solar neighborhood made with NASA's Chandra X-ray Observatory. About 200 years ago, William Herschel called these spherical clouds planetary nebulae because they were round like the planets. 18-inch (0.46 m)) and an OIII filter . (Image credit: European Southern Observatory) The term "planetary nebula" is a misnomer. Planetaries on the list are best viewed with a large aperture telescope (e.g.
