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. Hubble And Webb Pics, 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. Astronomers rejoiced as NASA’s Double Asteroid Redirection Test (DART) impactor slammed into its pyramid-sized, rugby ball-shaped target 11 million kilometers (6.8 million miles) from Earth on Monday night. Images taken by Earth-bound telescopes showed a vast cloud of dust expanding out of Dimorphos – and its big brother Didymos which it orbits – after the spaceship hit.
While those images showed matter spraying out over thousands of kilometers, Hubble And Webb Pics, 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. James Webb and Hubble can offer a view “within just a few kilometers of the asteroids and you can really clearly see how the material is flying out from that explosive impact by DART”, Fitzsimmons told AFP. “It really is quite spectacular,” he said. An image taken by James Webb’s Near-Infrared Camera (NIRCam) four hours after impact shows “plumes of material appearing as wisps streaming away from the center of where the impact took place”, according to a joint statement from the European Space Agency, James Webb and Hubble. Hubble images from 22 minutes, five hours, and eight hours after impact show the expanding spray of matter from where DART hit.
