October 13, 2009--If our home galaxy, the Milky Way, got into a tussle with its twin, the result might look like NGC 2623, a pair of colliding galaxies about 250 million light-years away.

Scientists using the Hubble Space Telescope created this recently released picture of the cosmic smashup from shots taken in 2007. The composite image reveals that the galaxies have merged at their cores, but huge clusters of young stars continue to form in the tails of gas and dust that trail what's left of each galaxy.
