Whirlpool Galaxy (M51), composite radio (yellow) and optical (blue) image. The Whirlpool galaxy is locked in a gravitational interaction with the smaller irregular galaxy NGC 5195 (above M51). M51 is around 50,000 light years in diameter, around half the size of our Milky Way. These two galaxies are around 37 million light years from Earth, in the constellation Canes Venatici. The optical data is from the Subaru Telescope, the Hubble Space Telescope and the Digitized Sky Survey. The radio data (at a wavelength of 12 centimetres) is from NRAO (National Radio Astronomy Observatory) and the VLA (Very Large Array).
