The galaxy was never in danger. For one thing, the Triangulum galaxy (M33), pictured, is much bigger than the tiny grain of rock at the head of the meteor. For another, the galaxy is much farther away -- in this instance 3 million light years as opposed to only about 0.0003 light seconds. Even so, the meteor's path took it angularly below the galaxy.
At the end, the meteor was gone in a second, but the galaxy will last billions of years. Your Sky Surprise: What picture did APOD feature on your birthday? (post 1995)
