JWST NIRCam and MIRI image of Arp 107, also known as UGC 5984.
In the near-infrared, we see older stars in white, as well as the bridge of gas and stars that runs between the galaxies. In the mid-infrared, we see young stars and star-forming regions in orange and red. The point of the collision between the two galaxies, is marked by the gap at the top of the spiral.

Hubble image of Arp 220, also known as IC 4553.
Arp 220 is the aftermath of a collision between two spiral galaxies. The collision set off a burst of star formation, creating star clusters seen as bluish-white bright knots in this image.
This image is part of a collection of 59 images of merging galaxies released to celebrate Hubble's 18th anniversary in 2008.

Kitt Peak National Observatory image of Arp 336, also known as NGC 2685.
NGC 2685 is a polar ring galaxy. It has a ring of gas, stars, and dust that orbits perpendicular to the plane of the galaxy, seen as unusual whorls, or helical filaments. These structures likely formed through an interaction which captured material from another galaxy.

Spitzer image of Arp 107, also known as UGC 5984.
Its infrared detectors mapped out faint regions of new star formation in this pair of colliding galaxies. Young star clusters (red) have formed along the ring-like tidal arm in this system. Older stars (blue) are seen the bridge that connects the two galaxies.

Hubble image of Arp 82, also known as NGC 2535 and NGC 2536.
NGC 2535 is the grand design spiral at center and NGC 2536 is its smaller companion at the end of one of its arms.
The larger galaxy's inner arms have evenly spaced "beads on a string" star clusters. This suggests recent gravitational interactions created shocks that led to a burst of star formation.

Hubble image of Arp 70, also known as VV 341.
Like its more famous cousin M51 (Arp 85, the Whirlpool galaxy), Arp 70 consists of a larger galaxy with two well-defined spiral arms interacting with a small companion. Such interactions have been linked to the production of grand-design spiral arms.
