NGC 4206 is about 70 million light-years away. It was imaged as part of a Hubble survey of nearby edge-on spiral galaxies made to measure the effect that the material between the stars, called the interstellar medium, has on the light that travels through it. Astronomers have been able to map the absorption and scattering of light by the material which causes objects to appear redder to distant observers.
