Hubble watches a spun-up asteroid coming apart! 💥💨☄️ A small asteroid has been caught in the process of spinning so fast it’s throwing off material, according to new data from @NASAHubble and other observatories.
Images from Hubble show two narrow, comet-like tails of dusty debris streaming from the asteroid Gault. Each tail represents an episode in which the asteroid gently shed its material — key evidence that Gault is beginning to come apart.
Piecing together Gault’s recent activity is an astronomical forensics investigation involving telescopes and astronomers around the world. All-sky surveys, ground-based telescopes, and space-based facilities like the Hubble Space Telescope pooled their efforts to make this discovery possible. Read more: https://go.nasa.gov/2V1KWmV
