description Little Ghost Nebula Overview
The Little Ghost Nebula, formally designated as NGC 6369, is a planetary nebula located in the southern constellation of Ophiuchus. It was first cataloged by the astronomer William Herschel in 1784. The dying star at its center emits ultraviolet radiation that strips away its outer layers, creating a faint, ghost-like spherical cloud of glowing gas and dust. Amateur astronomers frequently observe it using moderate to large telescopes due to its distinctive ring-like structure and relatively compact diameter.
help Little Ghost Nebula FAQ
Why is NGC 6369 called the Little Ghost Nebula?
Its small, pale ring can resemble a ghostly apparition through a telescope, leading to the Little Ghost nickname. NGC 6369 is a planetary nebula in Ophiuchus, not a cloud where planets are forming.
What created the Little Ghost Nebula?
It formed when a Sun-like star nearing the end of its life expelled its outer layers. Ultraviolet radiation from the hot stellar remnant now ionizes that gas and makes the expanding shell glow.
Can the Little Ghost Nebula be seen with a backyard telescope?
It can be observed with a moderate amateur telescope under dark skies, but its compact size and faint appearance make it challenging. An O III filter can improve the contrast of planetary nebulae like NGC 6369 against the background sky.
Who discovered the Little Ghost Nebula?
William Herschel discovered the object in 1784 during his systematic surveys of the sky. It was later entered in the New General Catalogue as NGC 6369.
