About image
NGC 2392, also known as "Eskimo Nebula" is a planetary nebula visible in the constellation Gemini.
It is bipolar and is formed by two envelopes; it is surrounded by the gases that made up the outer layers of a solar-type star 10,000 years ago.
The visible internal filaments are expelled by a strong wind of particles coming from the central star.
NGC 2392 is located at a distance of about 5,000 light years.
