First images of asteroid strike from Webb, Hubble telescopes

The James Webb and Hubble telescopes on Thursday revealed their initial images of a spacecraft deliberately crashing into an asteroid, marking the first time the two most powerful space telescopes have observed the same celestial object. While those images showed matter spraying out over thousands of kilometres, 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 see "within just a few kilometres of the asteroids and you can really clearly see how the material is flying out from that explosive impact by DART", Fitzsimmons told AFP. An image taken by James Webb's Near-Infrared Camera four hours after impact shows "plumes of material appearing as wisps streaming away from the centre of where the impact took place", according to a joint statement from the European Space Agency, James Webb and Hubble.
