It derives from the composition of three plates taken at blue, green and red wavelengths. The comet is characterised by two distinct tails. The plasma tail (blue at centre right) is produced by the interaction between the solar wind and the molecules of gases, such as carbon monoxide, sublimated from the nucleus. The dust tail (faint at top right) is formed by dust particles evaporated from the cometary nucleus and repelled by the radiation pressure of sunlight.
