A spectacular head-on collision between two galaxies has been captured by the NASA/ESA Hubble Space Telescope, which has the 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. Some of them can be seen through the interacting pair.
