DescriptionHubble-Webb side-by-side of Dimorphos ejecta, WFC3-NIRCAM compass image (+4-5 hours).png
English: Image is two columns, the column on the left is a photo with a black background and a bright blue spot at the center, labeled as Hubble. There is a bright haze around the dot, which is the Didymos-Dimorphos system, along with 5 diffraction spikes extending outward. The photo on the right is a black background with a bright red spot toward the middle of the image. The spot, which is the asteroid the Didymos-Dimorphos system after impact from DART, has 8 diffraction spikes extending out from its center. Also surrounding the asteroid is a haze of bright light with wispy tendrils extending outwards.
At the top right of the image, there are arrows indicating the direction of impact by the DART spacecraft. The direction of impact arrow points in the 5 o’clock direction. The to Sun arrow points in the 8 o’clock direction.
At the bottom right are compass arrows indicating the orientation of the image on the sky. The north arrow points in the 2 o’clock direction. The east arrow points in the 10 o’clock direction.
In the top left corner of each image are the filters used to create the image. For Hubble, F350LP is blue. For Webb, F070W is red.

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 Dimorphos 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 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).
