The Young Angel Nebula (or YAN, for short), also known as CelWP G-N1, is a supernova remnant nebula near Caloris. It hosts a white dwarf at its center, named Cassiel, which as of Release 18, has a single planet named Lucifer.

It's also designated as a mining zone by the Calorean Kingdom, due to its unusually high contents of metal and other heavy elements, and due to Desolation hosting blue-colored, water-rich gases.

Nomenclature[edit | edit source]

The nebula was named early on, by two Candacian space explorers named Renai Arana and Sarel Ranier. They noticed that the nebula looked like a young angel to them (granted, their angels look different from the ones Earth is used to), and so the name of Young Angel Nebula was submitted and accepted by the Calorean Royal Astronomical Society (CRAS).

Nowadays, the name of the nebula is considered as "misleading", since more recent surveys show that its shape resembles more like a steel pan than a young angel, and it only lives up to its name when viewed edge-on, like Arana and Ranier were.

General characteristics[edit | edit source]

The Young Angel Nebula is an unusually large supernova remnant, measuring around 34 light-years across. It's also classified as a starforming region, since several stars already formed in the nebula. The nebula is prominent for its unusually high presence of heavy elements, like iron and gold, which caused miners to nickname it the "Blue Metal Nebula".

Origin and the supernova[edit | edit source]

The nebula was formed in a Type II Supernova roughly 8.71 million years ago, and the progenitor was likely a red supergiant. Models of the supernova suggested that it reached a magnitude of -8 in Candacian skies, which means it even outshone Conal. Back then, what would become the YAN was estimated to be nearly 13,000 light-years away.

It's theorised that the vast majority of the iron from the supernova is still present today, which enabled widespread mining operations in the region.
