Description: For thousands of years, humanity was aware of five bright planets in the night sky. But in the 18th and 19th Centuries, astronomers found two additional planets beyond Saturn – Uranus and Neptune. After Neptune’s discovery in 1846, astronomers wondered if there were other planets hiding in the far flung depths of the outer solar system. Perhaps there was a “Planet X” out there? Success came in 1930 when a 24 year old astronomer who grew up on a farm in Kansas discovered the 9th planet, Pluto. Pluto has always held a unique fascination for us. Many people were bitterly disappointed when in 2006 it was downgraded to a ‘dwarf planet’. In July 2015 NASA’s New Horizons spacecraft flashed through the Plutonian system, taking incredibly detailed photographs of this distant world and its retinue of moons, revealing their astonishing beauty and complexity. Howard Simkover, who produced shows for the Montreal Planetarium, will speak about Pluto and the search for planets in the outer solar system.
