This image was captured using SIRPOL, the SIRIUS camera's mode of measuring circular polarity. It shows the degree of circular polarization of the Orion star-forming region. Yellow color expresses left-handed circular polarization where the electric vector of light is rotated anticlockwise. Red color expresses right-handed circular polarization. The black bar denoted by (A) expresses about 400 times the size of the solar system, and the bar by (B) shows about 100 times the size of the solar system.
