Astronomers captured an extraordinary image of the vast plume of dust and debris blasted from the surface of the asteroid struck by NASA’s spacecraft last week. The image shows at least a 10,000-kilometer-long dust trail.
The image was captured by NOIRlab’s SOAR telescope based in Chile. The plume or tail is called the ejecta and is similar to those seen trailing a comet. It was captured two days after NASA’s DART experiment where they deliberately crashed an unmanned spacecraft into the asteroid Dimorphos to see if they could successfully alter its course.
