Hubble/Webb Side-by-Side (WFC3/NIRCam Compass Image)
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.

The images are single exposures acquired by the WFC3 instrument on the Hubble Space Telescope and the by the NIRCam instrument on the James Webb Space Telescope. The color results from assigning a blue hue to a monochromatic (grayscale) hubble image and a red hue to a monochromatic (grayscale) Webb image. Blue: HST>F350LP Red: JWST>F070W
