This image captures a very small but unique interacting galaxy pair located about 3 degrees northeast of ξ Draconis, which forms the head of Dragon. The two elongated galaxies are in collision, causing them to distort into a shape resembling leaping dolphins. The eastern and western galaxies are distinguished as NGC6670E and NGC6670W, respectively. Detailed images with the Hubble Space Telescope confirm the presence of star-forming regions induced by the collision. With a total span of only about 1 minute, capturing them with an amateur telescope is quite challenging. The distance from the Milky Way Galaxy is estimated to be about 400 million light-years.
