The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.<\/p>\n

The right side of the galaxy is ablaze with star formation, shown in the plethora of young blue stars and star-incubating pinkish nebulas. The left side, however, looks intact. It contains hints of the galaxy’s previous spiral structure, which, at one time, was undergoing normal galactic evolution.<\/p>\n

The larger culprit galaxy, NGC 4490, is off the bottom of the frame. The two galaxies sideswiped each other millions of years ago and are now 24,000 light-years apart. The gravitational tug-of-war between them created rippling patches of higher-density gas and dust within both galaxies. This activity triggered a flurry of star formation.<\/p>\n

This galaxy is a nearby example of the kind of cosmic bumper-car activity that was more common billions of years ago when the universe was smaller and galaxies were closer together.<\/p>\n

NGC 4485 lies 25 million light-years away in the northern constellation Canes Venatici (the Hunting Dogs).<\/p>\n

This new image, captured by Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS), provides further insight into the complexities of galaxy evolution.<\/p>\n
