Predicting Impact Events
In 1994, Comet Shoemaker-Levy 9 created a large impact event on Jupiter, giving the scientific community a greater sense of urgency in detecting possible impact objects before they reached Earth. These efforts to detect near-Earth objects, known collectively as “Spaceguard”, have enjoyed both successes and failures. For example, in 2008, the Catalina Sky Survey discovered … Continue reading Predicting Impact Events → Continue reading
