Astronomers using the NSF’s NOIRLab’s SOAR telescope in Chile captured the vast plume of dust and debris blasted from the surface of the asteroid Dimorphos by NASA’s DART spacecraft when it impacted on 26 September 2022. In this image, the more than 10,000 kilometer long dust trail — the ejecta that has been pushed away by the Sun’s radiation pressure, not unlike the tail of a comet — can be seen stretching from the center to the right-hand edge of the field of view.

NASA Dart spacecraft rams into an asteroid in defense test

Scientists say the impact should have carved out a crater and hurled streams of rocks and dirt into space. Most importantly, though, scientists are hoping the collision altered the asteroid's orbit.

By Svetla Ben-Itzhak, The Conversation

Crashing the 1,340-pound DART probe into the small moonlet orbiting the asteroid Didymos should redirect its trajectory – and could be a model for how to save Earth in the future.
