'''Arp 299''' (parts of it also known as '''IC 694''' and '''NGC 3690''') is a pair of colliding galaxies approximately 134 million [[light-year]]s away in the [[constellation]] [[Ursa Major]].  Both of the galaxies involved in the collision are [[barred irregular galaxy|barred irregular galaxies]].  NGC 3690 was discovered by German-British astronomer [[William Herschel]] on 18 March 1790.<ref>

It is not completely clear which object is historically called ''IC 694''. According to some sources, the small appendage more than an arcminute northwest of the main pair is actually IC 694, not the primary (eastern) companion.<ref name="jhibbard">

The interaction of the two galaxies in Arp 299 produced young powerful [[starburst region]]s similar to those seen in [[II Zw 96]].<ref name="Goldaderetal1997">
