IC 59 and IC63 In Cassiopeia
Looking toward the constellation Cassiopeia, the skyscape features the swept back, comet-shaped clouds IC 59 (left) and IC 63 (lower centre). About 600 light-years distant, the clouds are slowly dissipating under the influence of ionizing ultraviolet radiation from hot,luminous blue-white star gamma Cas. Gamma Cas is physically located only 3 to 4 light-years from the nebulae, at the upper right centre of the frame.
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.
