The image taken by the telescope shows the resulting carnage in stunning detail, revealing a whopping 37 boulders ranging from three to 22 feet in diameter that were sent drifting away, according to a [Hubble statement](). The stunningly comprehensive snapshot could allow scientists to better understand what happened after DART bashed into the asteroid. In other words, they could provide valuable insights for future efforts that could potentially save humanity in the case of an asteroid that's on a collision course with Earth, the goal of the otherworldly demolition derby. "This is a spectacular observation — much better than I expected," said University of California at Los Angeles' David Jewitt, who's been studying these boulder movements, in the statement. ![]() ## Getting Swarmer The numbers align with scientists' predictions surprisingly well. "We see a cloud of boulders carrying mass and energy away from the impact target," said Jewitt. "The numbers, sizes, and shapes of the boulders are consistent with them having been knocked off the surface of Dimorphos by the impact." Scientists estimate that the mass of all the boulders combined represents roughly 0.1 percent of the mass of Dimorphos. The observation also highlights Hubble's incredible ability to spy on tiny objects from astronomical distances. "This tells us for the first time what happens when you hit an asteroid and see material coming out up to the largest sizes," Jewitt explained. "The boulders are some of the faintest things ever imaged inside our solar system." If all goes according to plan, we'll eventually get another up-and-close view courtesy of the European Space Agency's upcoming Hera spacecraft, which will visit the binary asteroid in late 2026. "The boulder cloud will still be dispersing when Hera arrives," Jewitt said in the statement. "It's like a very slowly expanding swarm of bees that eventually will spread along the binary pair's orbit around the Sun." **More on DART:** *[NASA Intrigued by Asteroid That Seems to Be Shooting Rocks Into Space]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
