NGC 1360_ Robin's Egg Nebula

"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.

The central star of the system was suspected to be binary since 1977, but was only confirmed in 2017. The central source consists of a low-mass O-type star and a white dwarf.

NGC 1360 was discovered in January 1868 by the German astronomer Friedrich August Theodor Winnecke."(Wikipedia)
