Interacting galaxies (colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. An example of a minor interaction is a satellite galaxy disturbing the primary galaxy's spiral arms. An example of a major interaction is a galactic collision, which may lead to a galaxy merger.

Astronomers discovered that as many as 25% of galaxies are currently merging with others. Probably even more are gravitationally interacting with their neighbors, with subsequent exchanges of stars and effects on the structures of both galaxies.

May 3, 2023 · This new image from NASA’s Hubble Space Telescope shows interacting galaxies known as AM 1214-255. These galaxies contain active galactic nuclei, or AGNs. An AGN is an extraordinarily luminous central region of a galaxy. Its extreme brightness is caused by matter whirling into a supermassive black hole at the galaxy’s heart.

Oct 7, 2022 · Though they appear serene and unperturbed, the two are subtly warping one another through a mutual gravitational interaction that is disrupting and distorting both galaxies. Hubble’s Advanced Camera for Surveys captured this drawn-out galactic interaction.

Jul 12, 2024 · NASA’s James Webb Space Telescope’s mid-infrared view of interacting galaxies Arp 142 seems to sing in primary colors. The Egg shows up as a tiny, teal-colored oval, because it is made up of old stars and has lost or used up most of its gas and dust.

The Antennae galaxies provide a stunning multi-wavelength view of galaxy interaction and all the resulting phases of the stellar lifecycle. Interacting galaxies typically swing by each other multiple times, each time compressing gas to form new stars.

Interacting Galaxies is the term given to when two or more galaxies interfere with one another, that is, they interact. There are two types of Interacting Galaxies, and they are:- A galaxy interacting with another galaxy can kick off star creations.

Apr 24, 2008 · This visualisation of a galaxy collision created by a supercomputer simulation shows the entire collision sequence, and compares the different stages of the collision with different interacting galaxy pairs observed by the NASA/ESA Hubble Space Telescope.

Starbursts: When galaxies interact and merge, their interstellar gas can be compressed and driven to the inner regions through shocks and gravitational torques, triggering intense starbursts. And whats's with these tails?

Jan 10, 2020 · When galaxies cluster together and interact, interesting things can happen that affect their shapes and the stars they contain. Let's find out more!
