After DART crash, asteroid Dimorphos sports a tail of debris

A new stunning image shows that two days after NASA’s Double Asteroid Redirection Test (DART) spacecraft slammed into the asteroid Dimorphos, the space rock had grown a tail of glowing debris extending thousands of miles. 

The comet-like tail is made of dust and debris was blasted from the surface of Dimorphos, part of a double asteroid system, by the intentional impact of DART, the first mission designed to test whether such a collision could divert a hypothetical asteroid threatening to hit Earth. Dimorphos’ new tail was imaged by astronomers Teddy Kareta from the Lowell Observatory and Matthew Knight from the U.S. Naval Academy using the 4.1-meter Southern Astrophysical Research (SOAR) Telescope, at the National Science Foundation-funded NOIRLab’s Cerro Tololo Inter-American Observatory in Chile.
