Update: Since this episode originally aired, the bill to make Pluto the official state planet of Arizona was signed into law.

Science was forever changed, thanks to an observatory in Flagstaff named after Percival Lowell, one of the first minds to explore the potential of water on Mars and theorize about undiscovered planets.

In 1930, the Lowell Observatory announced the discovery of a ninth planet at the end of the solar system: Pluto.

Now, almost 100 years later, a state representative is proposing to make Pluto the official state planet.

This week on Valley 101, a podcast about metro Phoenix and beyond, we dive into the history of Pluto, the scientific breakthrough in its findings and why an elected official wants it to represent Arizona.
