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.
