Galileo, closing in on Jupiter, was in a position to image the impacts directly, though from a great distance. |

In a wavelength of infrared strongly absorbed by methane, Jupiter appears dark. A fresh impact has just rotated into view. Hot material high in Jupiter's atmosphere emits copious infrared that swamps the detector. |

|
Another impact later in the series. Previous impacts show as a string of glowing dots in infrared. |
