[edit]DescriptionHubble-Webb Side-by-Side of Dimorphos Ejecta (2022-047).tiff |
English: For the first time, NASA’s James Webb Space Telescope and Hubble Space Telescope have taken simultaneous observations of the same target.
These images, Hubble on left and Webb on the right, show observations of the Didymos-Dimorphos system several hours after NASA’s Double Asteroid Redirection Test (DART) intentionally impacted the moonlet asteroid. It was the world’s first test of the kinetic impact technique using a spacecraft to deflect an asteroid by modifying its orbit. Both Webb and Hubble observed the asteroid before and after the collision took place. Scientists will use the combined observations from Hubble and Webb to gain knowledge about the nature of the surface of Dimorphos, how much material was ejected by the collision, how fast it was ejected, and the distribution of particle sizes in the expanding dust cloud. In the coming months, scientists will also use Webb’s Mid-Infrared Instrument (MIRI) and Near-Infrared Spectrograph (NIRSpec) to observe ejecta from Dimorphos further. Spectroscopic data will provide researchers with insight into the asteroid’s composition. Hubble will monitor Dimorphos ten more times over the next three weeks to monitor how the ejecta cloud expands and fades over time. Hubble observations were conducted in one filter, WFC3/UVIS F350LP (assigned the color blue), while Webb observed at F070W (0.7 microns, assigned the color red). NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.
