One of the most important events for modern astronomy was the series of collisions, during a single week in 1994, of more than a dozen large objects with Jupiter. ███ █████████ ██ █████ ████████ █████ ████ ██████ ████ ██ ███ █████ ██████████████ ██ ████████ ██ ██████████ ████ ██████ ██ █████ ██ ██████ █████ ███ ████ ██ █████ ████████ ██ ███ ███████████ ██ ██ ████ ████ ████ ██ ███ ███████ █████████ ██████████ ██ █████████ █████ ██████████ ███ ████ ███ █████ ███ ████████ ██ ████ ██████ ████ ████
Summary
The main conclusion is that none of the SL9 comet’s fragments penetrated Jupiter’s lower atmosphere, and the SL9 comet was made of rock instead of ice.
This is supported by the intermediate conclusion that there was no water involved in the collision between the SL9 comet fragments and Jupiter.
The intermediate conclusion is supported by the fact that the collision resulted in formations that show “no signs of water.”
Notable Assumptions
The author assumes that if the collision resulted in formations that show “no signs of water,” then that proves that the collisions did not involve water.
The author assumes that if the collisions did not involve water, then the comet fragments could not have penetrated to Jupiter’s lower atmosphere.
The author assumes that if the collisions did not involve water, then the comet was composed of rock instead of ice.
