Scientists released the OSIRIS Image Viewer to make the amazing images of comet 67P – acquired by the Rosetta spacecraft – easily accessible on the internet.
Comet 67P/Churyumov-Gerasimenko in the days before its perihelion, or closest point to the sun, in August, 2015. The image is intentionally overexposed to show that the number of dust jets leaving the surface during the comet's most active phase is, as these scientists said,
