In the case of NASA&#8217;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 &#8212; 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&#8217;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&#8217;s larger companion: asteroid Didymos. Most recently, images show that the Didymos &#8211; Dimorphos system has developed comet-like tails. via NASA <a href=\"https:\/\/apod.nasa.gov\/apod\/ap221005.html\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>What happens if you crash a spaceship into an asteroid?
