An international study led by Northwestern University in the US observed a rare “cosmic impact” in a nearby planetary system using the Hubble Space Telescope, revealing that dust clouds may disguise themselves as planets for several years. This discovery helps to further reveal the mechanism of planet formation and provides an in-depth understanding of the structural characteristics of asteroids. It is of great significance for planetary defense plans such as the double asteroid redirection test. The research results were published in the new issue of “Science” magazine.
