Since the ‘80s, when Voyager 2 discovered extremely high atmospheric winds on Uranus and Neptune, the vertical extent of those winds has been a puzzle.

The Tea Party and the Politics of Paranoia

Tea party members claim the movement reflects basic American conservative principles such as limited government and fiscal responsibility.
