Interacting Galaxies NGC 2445 & NGC 2444: Arp 143 | Hubble

Interacting Galaxies NGC 2445 & NGC 2444 in Lynx | Hubble

A spectacular head-on collision between two galaxies has been captured by the NASA/European Space Agency Hubble Space Telescope. It displays an unusual triangular-shaped star-birthing frenzy.

The interacting galaxy duo is collectively called Arp 143. The pair contains the distorted, star-forming spiral galaxy NGC 2445, at right, along with its less flashy companion, NGC 2444, at left. This frenzied action takes place against the tapestry of distant galaxies. They can be seen through the interacting pair.
