Planetary scientist David Jewitt has led an unprecedented observation of the aftermath of NASA’s DART experiment, a high-speed asteroid collision, using the Hubble Space Telescope. This groundbreaking mission involved impacting the asteroid Dimorphos at approximately 14,000 miles per hour with the intention of slightly altering its orbital path. Post-impact, the Hubble captured images of 37 boulders, ranging from three to 22 feet in size, drifting from the asteroid’s surface at a pace just over half a mile per hour. This surprising phenomenon represents around 0.1% of Dimorphos’ total mass. Contrary to initial predictions, the boulders weren’t fragmented pieces from the … Continue reading Stellar Collision: Hubble Unveils Aftermath of NASA’s DART Experiment
