IC 59, IC 63 and Gamma Cas

IC 59 (upper) and IC 63 nebulae lie about 600 light-years distant. They are slowly dissipating under the influence of ionizing ultraviolet radiation from hot, luminous star gamma Cas. Gamma Cas is physically located only 3 to 4 light-years from the nebulae. In fact, slightly closer to gamma Cas, IC 63 is dominated by red H-alpha light emitted as the ionized hydrogen atoms recombine with electrons. Farther from the star, IC 59 shows proportionally less H-alpha emission but more of the characteristic blue tint of dust reflected star light.

Gamma Cassiopeiae and IC 63 and IC 59 emission and reflection nebulae

A hot, variable, and rapidly rotating star about 600 light-years distant, Gamma Cas also ionizes surrounding interstellar material, including the wispy IC 63 (left) and IC 59 emission and reflection nebulae. The two faint nebulae are physically close to Gamma Cas, separated from the star by only a few light-years.
