description IC 63 Overview

IC 63, unofficially nicknamed the Ghost of Cassiopeia, is an emission and reflection nebula located roughly 550 light-years away in the constellation Cassiopeia. The structure is physically shaped and illuminated by the high-energy radiation emitted by the nearby massive star Gamma Cassiopeiae. It presents a distinct combination of glowing red hydrogen gas and reflecting blue dust, making it a frequent target for astrophotography. The nebula is categorized as a stellar nursery where new star formation is actively taking place.

help IC 63 FAQ

Why is IC 63 nicknamed the Ghost of Cassiopeia?

IC 63 is nicknamed the Ghost of Cassiopeia due to its eerie, wispy shape and its location in the constellation Cassiopeia. Its striking, ghost-like appearance is caused by the radiation from the nearby massive star Gamma Cassiopeiae.

What type of nebula is IC 63?

IC 63 is classified as both an emission and reflection nebula. Parts of the hydrogen gas cloud are glowing red from ionizing radiation, while other parts are reflecting the blue light emitted by the nearby star.

Where is IC 63 located?

IC 63 is located in the northern constellation Cassiopeia. It is situated roughly 550 light-years away from Earth, making it a relatively close neighbor in astronomical terms.

What is causing the shape of the IC 63 nebula?

The nebula's distinct, towering shape is being sculpted by the intense ultraviolet radiation from Gamma Cassiopeiae. This radiation is slowly eroding and boiling away the nebula's cosmic gas, a process astronomers call photoevaporation.
