Description

NGC 1360, also known as the Robin's Egg Nebula, is a planetary nebula in the constellation of Fornax. It was identified as a planetary nebula due to its strong radiation in the OIII bands. Reddish matter, believed to have been ejected from the original star before its final collapse, is visible in images.

Planetary nebulae can take a wide variety of shapes. Most show a distinctive and well marked symmetry, which can vary from more or less spherical, to a doughnut-like annulus or to bi-polar, butterfly-like objects. Planetary nebulae also usually have well-defined boundaries, sometimes even a shell-like structure. For reasons that are not understood, NGC 1360 in Fornax defies all these conventions, yet its colour still clearly identifies it as a planetary nebula. The green hue is oxygen, excited by the hot central star, and to the north-east of the nebula is a faint red smudge, probably traces of material ejected before the star became a true planetary nebula.
