About 300 million light-years away, four galaxies are colliding in a flurry of superheated gas and X-rays, and a Hungarian astrophotographer captured it in October. A half-degree away in the sky, in the constellation Pegasus, (but about 250 million light-years closer to Earth) is the galaxy NGC 7331, a spiral galaxy similar to our own Milky Way.
