Grozeth Nebula

The Grozeth Nebula (N44) is an emission nebula with superbubble structure located in the Bacterian Home Galaxy. It is approximately 1,000 light-years wide.

Structure

The Grozeth Nebula has a smaller bubble structure inside known as the Eye of Arturoth. The superbubble structure of Grozeth itself is shaped by the radiation pressure of a 40-star group located near its center; the stars are blue-white, very luminous, and incredibly powerful. The Eye of Arthuroth has been shaped in a similar manner; it has a hot, massive central star with an unusually powerful stellar wind that moves at 7 million kilometers per hour. This is because it loses material at a rate of approximately 1,000,000,000,000,000 tons per year. However, varying density in the Grozeth nebula has caused the formation of several dust pillars that may conceal star formation. This variable density is likely caused by previous supernovae in the vicinity of Grozeth; many of the stars that have shaped it will eventually also end as supernovae. The past effects of supernovae are also confirmed by the fact that Grozeth emits x-rays.

The Grozeth Nebula is classified as an emission nebula because it contains large regions of ionized hydrogen. However, the three strongest emission lines in the nebula are singly ionized oxygen atoms, which emit at an ultraviolet wavelength of 372.7 nm, doubly-ionized oxygen atoms, which emit at a blue-green wavelength of 500.7 nm, and neutral hydrogen atoms, which emit the hydrogen-alpha line at a red wavelength of 656.2 nm.
