Nicknamed the spare-tyre nebula, [47] IC 5148 is a planetary nebula located around 1 degree west of Lambda Gruis. [48] Around 3000 light-years distant, it is expanding at 50 kilometres a second, one of the fastest rates of expansion of all planetary nebulae. [47] Northeast of Theta Gruis are four interacting galaxies known as the Grus Quartet. [49]
Barnard's Loop (catalogue designation Sh 2-276) is an emission nebula in the constellation of Orion. It is part of the Orion molecular cloud complex which also contains the dark Horsehead and bright Orion nebulae. The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to ...

The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. [1] It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.
The nebula contains ions of extremely high ionization potential. [20] The helium hydride ion, thought to be the earliest molecule to have been formed in the Universe (about 100,000 years after the Big Bang), was detected in 2019 for the first time in space in NGC 7027. [21] [22] There is also evidence for the presence of nanodiamond in NGC 7027 ...

M57, also known as the "Ring Nebula" and NGC 6720, [69] at a distance of 2,550 light-years from Earth is one of the best known planetary nebulae and the second to be discovered; its integrated magnitude is 8.8. [70] It was discovered in 1779 by Antoine Darquier, 15 years after Charles Messier discovered the Dumbbell Nebula. [71]
It is known as the Blue Snowball Nebula, Snowball Nebula, and Caldwell 22. This nebula was discovered October 6, 1784 by the German-born English astronomer William Herschel . In the New General Catalogue it is described as a "magnificent planetary or annular nebula, very bright, pretty small in angular size , round, blue, variable nucleus".
