Planets Discovery
End Show

• Instead of looking in the sky to find Neptune,
  Astronomers found it with math. After Uranus was
  discovered, scientists were confused when truing
  to figure out its orbit. They hypothesized that
  there was another planet farther from the sun
  interfering with Uranuss orbit. Their hypothesis
  was correct. A French astronomer named Leverrier
  and an English astronomer named John Couch Adams
  did the math that said Neptune should be. German
  astronomer Johann Galle observed it.

Color of the Big Blue.

• Neptune's color (blue) is mainly the result of
  absorbing red light by methane in the atmosphere
  but, there is also some more currently-unidentifie
  d chromophore which gives the clouds their blue
  color.
