This week we announced a second asteroid collision discovered around the nearby star Fomalhaut in the last 20 years. Here I took my original Hubble Space Telescope discovery image and imagined what Fomalhaut would look like if we could speed up 2,000 years of asteroid collisions into 10 seconds of video. The right side of Fomalhaut's dusty debris belt would sparkle with these impacts as if we were watching fireworks going off in the system.
