After the successful impact of NASA’s DART mission on the Dimorphos asteroid, scientists have encountered a series of unexpected outcomes, the latest being the unanticipated lengthening of the asteroid’s orbital period around its larger partner, Didymos.
Astronomers using the Hubble Space Telescope have detected nearly 40 boulders near Dimorphos—the target of NASA’s wildly successful DART experiment to deflect a non-threatening asteroid. This isn’t exactly positive news, since it suggests that hitting a bona fide hazardous asteroid might create a cluster of possibly…
