Hubble captures a spectacular three-way gravitational tug of war between galaxies

This system - named Earp 195 - appears in the Atlas of Peculiar Galaxies, a list that shows some of the weirder and wonderful galaxies in the universe

A dramatic trio of galaxies takes center stage in this latest "Picture of the Month" captured by NASA's Hubble Space Telescope and the European Space Agency, which captures a spectacular three-way gravitational tug of war between galaxies. This system — named Arp 195 — appears in the Unique Galaxy Atlas, A list featuring some of the weirder and wonderful galaxies in the universe.

Viewing time with the Hubble Space Telescope is very valuable, so astronomers don't want to waste even a second. The Hubble observation schedule is calculated by a computer algorithm that allows the spacecraft to occasionally collect additional images of data between longer observations. This image of the trio of colliding galaxies in Arp 195 is such an image. These additional observations not only provide spectacular images—they also help identify promising targets for follow-up with telescopes such as NASA's James Webb Space Telescope and the soon-to-be-launched European and Canadian space agencies.

  1. Halton Earp showed clear physical connections between galaxies and quasars with vastly different redshifts. The science of astrophysics had to ignore everything it claimed so as not to stir up storms in the establishment. The universe is not expanding. There was no big bang. The creation story would have sounded more logical already...

  2. How do you see there "a three-way gravitational tug of war in intergalactic interaction"???? I see in the picture a double-sided tug of war inside a galaxy...
