The galaxy NGC 4485 altered by a cosmic clash

A new image captured by the Hubble Space Telescope’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) instruments portrays the galaxy NGC 4485. It’s an irregular galaxy, which means that its shape is not among the normal ones for galaxies, a consequence of its passage through a much larger neighbor, NGC 4490, which altered the balance inside it and among other things also started the formation of new stars.
