The Engraved Hourglass Nebula, formally MyCN 18, is a young planetary nebula located within the Musca constellation. It’s notable for its distinctive bipolar shape – resembling an hourglass – captured dramatically by the Hubble Space Telescope in 1996. This formation originates from a dying star, sp...
The Ghost of Saturn Nebula, designated NGC 7009, is a planetary nebula located in the constellation of Aquarius. English astronomer William Herschel discovered it in 1782, observing its distinct, roughly Saturn-like shape. The nebula is noted for its ansae, which are extensions of nebulosity flankin...
The Robin's Egg Nebula, NGC 1360, is a large planetary nebula in Fornax discovered in 1868 and distinguished by its blue-green glow.
The Blue Planetary Nebula, NGC 3918, is a bright planetary nebula in Centaurus discovered by John Herschel in 1834 and noted for its vivid color.
NGC 1514, often referred to as the Crystal Ball Nebula, is a planetary nebula located in the constellation Taurus. It was discovered by astronomer William Herschel in 1790, and its observation forced him to revise his theories, recognizing that nebulosity could surround a central star rather than ju...
NGC 7026 is a bipolar planetary nebula in the constellation Cygnus, discovered by American astronomer Lewis Swift in 1873 (not Edward Swift). The nebula features a distinctive butterfly or hourglass shape with two lobes of gas extending outward from a central star, which is in the final stages of st...
Sharpless 2-71 is an irregular planetary nebula in Aquila, discovered by Rudolph Minkowski in 1946 and studied for its unusually complex stellar system.
The Cheerio Nebula, NGC 6337, is a ring-shaped planetary nebula in Scorpius whose central binary produced its conspicuous toroidal structure.
The Fine-Ring Nebula, Shapley 1, is a planetary nebula in Norma whose nearly circular shell surrounds a binary with a 2.9-day orbit.
IC 4663 is a planetary nebula in the constellation Scorpius, formed from material expelled by a star near the end of its evolution. Its central star has a hydrogen-deficient spectrum dominated by helium, a composition that has attracted attention in studies of planetary-nebula nuclei and stellar evo...
The Magic Carpet Nebula, NGC 7027, is a young planetary nebula in Cygnus whose dense, rapidly expanding gas surrounds a hot stellar remnant.
The Spiral Planetary Nebula, formally designated as NGC 5189, is a planetary nebula located in the southern constellation of Musca. Scottish astronomer James Dunlop first catalogued the object in 1826, originally misclassifying it as a non-planetary object due to its unusual appearance. The dying st...
The Raspberry Nebula, IC 418, is a compact planetary nebula in Lepus whose intricate shell was imaged in fine detail by the Hubble Space Telescope.
The Pink Pillow Nebula, NGC 7027, is a compact young planetary nebula in Cygnus, notable as one of the brightest such objects at radio wavelengths.
The Headphone Nebula, formally designated Jones-Emberson 1, is a faint planetary nebula located in the northern constellation Lynx. Discovered in 1939, it spans approximately four light-years across and possesses a central white dwarf star. Its common name derives from its distinctive headphone-like...
