Multiple asteroids may have contributed to dinosaur extinction, scientists reveal

New research points to a second asteroid impact possibly contributing to the extinction of dinosaurs, challenging the long-held belief of a single impact event. This discovery comes as the European Space Agency (ESA) readies its Hera spacecraft for launch to study the results of NASA's asteroid redirection experiment from 2022. These missions aim to enhance our understanding of asteroid impacts and strengthen future planetary defense strategies in case of potential threats.
