IC 2220 is a reflection nebula 1200 light-years away in the constellation Kiel des Schiff , which is recorded in the index catalog . The object was discovered by DeLisle Stewart on March 30, 1900 .
The reflection nebula consists of a cloud of gas and dust that is illuminated from within by the star HD 65750. The star belongs to the red giant type and has five times the mass of our sun . Although it is comparatively young at 50 million years old, it is in a significantly advanced stage of its life. During this phase, the star continuously loses part of its mass to the environment. This material cools down and forms the gas and dust cloud. The dust consists of elements such as carbon and simple, heat-resistant molecules such as titanium dioxide and calcium oxide . For IC 2220, detailed investigations of the object in infrared light have shown that silicon dioxide is probably the component that is most likely responsible for the reflection of star light.
