Asteroid struck by NASA leaves a 10,000 km debris trail; image surfaces
A photograph showed that a NASA-initiated asteroid strike on September 26 had left a 10,000-kilometer-long growing, comet-like trail of debris. Astronomers in Chile took the photo two days after the collision. In its initial attempt to move an asteroid in space, NASA's Double Asteroid Redirection Test aircraft collided with the asteroid on September 26.
