QUESTION: Is Jupiter's atmosphere something like thick soup? You stick your finger into it then pull it out and it takes a while for it to fill the indentation back up. How long will it take Jupiter's atmosphere to refill the hole the probe makes? ANSWER from Nagin Cox on Feb. 6,1996: Jupiter's atmosphere is gaseous so any object that penetrates it does not really make a hole. Think of a bullet going through the air - the air fills in the "hole" made by the bullet instantaneously. Similarly, the Jovian atmosphere filled in the space the probe passed through very quickly.
