Gemini Observatory two-color composite image of C/2019 Q4 (Borisov) which is the first interstellar comet ever identified. This image was obtained using the Gemini North Multi-Object Spectrograph (GMOS) from Hawaii’s Maunakea. The image was obtained with four 60-second exposures in bands (filters) r and g. Blue and red dashes are images of background stars which appear to streak due to the motion of the comet. Composite image by Travis Rector. Image Credit: Gemini Observatory/NSF/AURA

This image of the giant planet Jupiter, by NASA's Hubble Space Telescope, reveals the impact sites of fragments "D" and "G" from Comet Shoemaker-Levy 9. The large feature was created by the impact of fragment "G" on July 18, 1994 at 3:28 a.m. EDT. It entered Jupiter's atmosphere from the south at a 45-degree angle, and the resulting ejecta appears to have been thrown back along that direction. The smaller feature to the left of the fragment "G" impact site was created on July 17, 1994, at 7:45 a.m. EDT by the impact of fragment "D". Credits: H. Hammel, MIT and NASA
