• Galactic Merger In Starlight 9.11.2020 VIDEO: This shows a 3-color video of the starlight in this merger, processed through observed filters with the SUNRISE radiative transfer code. Credit: Patrick Jonsson • This movie shows a typical simulation of major galaxy merger. In the merger, two Milky Way-like disk galaxies with a 2:1 mass ratio are placed in an initial parabolic orbit. The disks are constructed in equilibrium, with properties corresponding to observed disk galaxies, and include stel

A Tour of Galaxy Merger Arp-Madore 417-391 in Eridanus | Hubble FriendsofNASA.org: The galaxy merger Arp-Madore 417-391 steals the spotlight in this image from the NASA/European Space Agency Hubble Space Telescope. The Arp-Madore catalog is a collection of particularly peculiar galaxies spread throughout the southern sky, and includes a collection of subtly interacting galaxies as well as more spectacular colliding galaxies. Arp-Madore 417-391, located around 670 million light-years away in the
