Interacting Galaxies
| Galaxies | Data | Notes |

|
The Magellanic Clouds are being tidally disrupted by the Milky Way Galaxy, resulting in the Magellanic Stream drawing a tidal tail away from the LMC and SMC, and the Magellanic Bridge drawing material from the clouds to our galaxy. | |
|
The smaller galaxy NGC 5195 is tidally interacting with the larger Whirlpool Galaxy, creating its grand design spiral galaxy architecture. | |
|
These three galaxies interact with each other and draw out tidal tails, which are dense enough to form star clusters. The bridge of gas between these galaxies is known as Arp's Loop. | |
|
NGC 6872 is a barred spiral galaxy with a grand design spiral nucleus, and distinct well-formed outer barred-spiral architecture, caused by tidal interaction with satellite galaxy IC 4970. | |
| Tadpole Galaxy | The Tadpole Galaxy tidally interacted with another galaxy in a close encounter, and remains slightly disrupted, with a long tidal tail. |

| Arp 299 (NGC 3690 & IC 694) | These two galaxies have recently collided and are now both barred irregular galaxies. |

| Mayall's Object | This is a pair of galaxies, one which punched through the other, resulting in a ring galaxy. |

Famous quotes containing the word galaxies:
“Don’t you see what’s at stake here? The ultimate aim of all science—to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet.”
—Walter Reisch (1903–1963)
