A dramatic trio of galaxies is at the center of the scene in this image from the NASA/ESA Hubble Space Telescope, which captures a three-way gravitational pull between interacting galaxies. Known as the Arp 195, this system is featured in the Atlas of Bizarre Galaxies, a list that shows some of the weirder and more wonderful galaxies in the universe.
Observing time with Hubble is extremely valuable, so astronomers don’t want to waste a second. The schedule of Hubble observations is calculated using a computer algorithm that allows the spacecraft to occasionally collect additional snapshots of data between longer observations.
This image of the colliding galaxy trio in Arp 195 is one such snapshot.
Extra observations like these do more than provide spectacular images; they also help identify promising targets to follow with the use of telescopes such as the upcoming NASA/ESA/CSA James Webb Space Telescope.
