Answer to Question 1

Helium seems to be condensing and raining downward toward Saturn's mantle.

Answer to Question 2

At 98 degrees, Uranus is flopped over on its side, and can have its pole pointing directly at the Sun, as it did when Voyager 2 passed it in 1986. Neptune's tilt is a more normal 29 degrees.
