his pretty planetary nebula, cataloged as NGC 6369, was discovered by 18th century astronomer William Herschel as he used a telescope to explore the medicinal constellation Ophiucus. Round and planet-shaped, the nebula is also relatively faint and has acquired the popular moniker of Little Ghost Nebula.

A Fox Fur, a Unicorn, and a Christmas Tree Nebula. A star forming region cataloged as NGC 2264, the complex jumble of cosmic gas and dust is about 2,700 light-years distant and mixes reddish emission nebulae excited by energetic light from newborn stars with dark interstellar dust clouds. Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae.

The Egg Nebula (also known as RAFGL 2688 and CRL 2688) is a bipolar protoplanetary nebula approximately 3,000 light-years away from Earth. Its peculiar properties were first described in 1975 using data from the 11 µm survey obtained with sounding rocket by Air Force Geophysical Laboratory (AFGL) in 1971 to 1974. (Previously, the object was catalogued by Fritz Zwicky as a pair of galaxies.) en.wikipedia.org/...
Crimson Flares. NGC 6188 is an emission nebula about 4000 ly away in the constellation Ara. Within NGC 6188 is an open cluster of bright young stars (the Ara OB1 association) known as NGC 6193. In the bottom left hand corner is a small emission nebula NGC 6164-5. The star in the middle of the nebula is believed to have created the gas cloud and causes it to glow by virtue of the UV light it emits. That gas was likely thrown off from the star, possibly by its fast rotation.
Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023 this is not the only nebula in the sky to evoke the imagery of flowers.
