Hubble Captures Movie of DART Asteroid Impact Debris
Space Telescope Science Institute (STScI)A time-lapse movie from the Hubble Space Telescope captures the impact of asteroid Dimorphos when it was deliberately hit by NASA's DART spacecraft on Sept. 26, 2022. The movie shows three overlapping stages of the impact aftermath: the formation of an ejecta cone; the spiral swirl of debris caught up along the asteroid's orbit about its companion asteroid; and the tail swept behind the asteroid by the pressure of sunlight. Later on, Hubble records the tail splitting in two.
