The James Webb and Hubble telescopes on Thursday revealed their first images of a spacecraft deliberately smashing into an asteroid, as astronomers indicated that the impact looks to have been much greater than expected.
The world's telescopes turned their gaze towards the space rock Dimorphos earlier this week for a historic test of Earth's ability to defend itself against a potential life-threatening asteroid in the future.
While those images showed matter spraying out over thousands of kilometers, the James Webb and Hubble images"zoom in much closer", said Alan Fitzsimmons, an astronomer at Queen's University Belfast involved in observations with the ATLAS project. The images depict an impact that looks"a lot bigger than we expected," said Carnelli, the manager of the ESA's Hera mission which intends to inspect the damage in four years.The Hera mission, which is scheduled to launch in October 2024 and arrive at the asteroid in 2026, had expected to survey a crater around 10 meters in diameter.
