Expanding Plume from DART's Impact
Explanation: What happens if you crash a spaceship into an asteroid? In the case of
NASA's
DART spaceship and the small asteroid
Dimorphos, as happened last week, you get
quite a plume. The goal of the planned impact was
planetary protection -- to show that the path of an asteroid can be
slightly altered, so that, if done right, a big space rock will
miss the Earth. The high brightness of the plume, though, was
unexpected by many, and what it means remains a topic of research. One possibility is that 170-meter wide
Dimorphos is primarily a
rubble pile asteroid and the collision dispersed some of the rubble in the pile. The
featured time-lapse video covers about 20 minutes and was taken from the
Les Makes Observatory on
France's
Reunion Island, off the southeast coast of southern Africa. One of
many Earth-based observatories following the impact, the initial dot is primarily Dimorphos's larger companion: asteroid
Didymos. Most recently, images show that the Didymos - Dimorphos system has
developed comet-like tails.
