NGC-4490 Galaxy in Canes Venatici
NGC-4490, a distorted spiral galaxy located in the constellation of Canes Venatici. This galaxy and its smaller companion, NGC-4485, to the west, are in tidal interaction with each other. These galaxies have already reached their closest approach point, and are now pulling away from each other. A tidal stream of stars has been pulled off of NGC-4490 and stretches towards NGC-4485, which lies only 24,000 light years away (less than the distance from Earth to the center of our own Milky Way galaxy). This tidal interaction has triggered immense bursts of star formation within both galaxies. This pair lies 24 million light years from Earth.
