Didymos-Dimorphos System on October 11 (Compass)

A bright blue spot is at the left-center of the image, which has a black background. The spot is the Didymos-Dimorphos system after impact from the DART spacecraft. The center bright spot has 3 diffraction spikes extending from its core at the 1 o’clock, 7 o’clock, and 10 o’clock positions. There is a small amount of dusty haze just below the southern pole of the center dot. Two tails of ejecta that appear as white streams of material extend out from the center at the 2 o’clock and 3 o’clock positions.

Two tails of dust ejected from the Didymos-Dimorphos asteroid system are seen in new images from NASA’s Hubble Space Telescope, documenting the lingering aftermath of the NASA’s Double Asteroid Redirection Test (DART) impact.

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 10 o’clock direction. The ‘to Sun’ arrow points in the 8 o’clock direction.

Following impact, Hubble made 18 observations of the system. Imagery indicates the second tail formed between Oct. 2 and Oct. 8.

At the bottom right are compass arrows indicating the orientation of the image on the sky. The north arrow points in the directly straight up. The east arrow points to the left in the 9 o’clock direction. In the top left corner of each image are the filters used to create the image. For Hubble, F350LP is blue.

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

The images are separate exposures acquired by the WFC3 instrument on the Hubble Space Telescope. The color results from assigning a blue hue to a monochromatic (grayscale) image.

Two images blink back and forth between one another on a black background. On both, a bright blue spot appears at the center of the image. The spot is the Didymos-Dimorphos system after impact from the DART spacecraft. In the first frame, captured on October 8, the center bright spot has 3 diffraction spikes extending from its core at the 1 o’clock, 7 o’clock, and 10 o’clock positions. There is a small amount of dusty haze in the region surrounding the lower left of the core. Two tails of ejecta that appear as white streams of material extend out from the center at the 2 o’clock and 3 o’clock positions. There is a clump of dusty haze visible above the northern tail. In the second frame, captured on October 11, there are some small differences visible in the system. The dusty haze in the lower left below the core has shifted closer to true south. The haze above the northern tail has spread out.
