Synopsis: "For thousands of years we only knew of the classical planets out as far as Saturn. That all changed in 1781 when William Herschel discovered the planet Uranus and at a stroke doubled the then-known size of the Solar System. Neptune soon joined the planet club while Pluto had a brief membership during the 20th century.
Astronomers have found though that the outer solar system is a far more dynamic place than was originally thought with various classes of asteroid-sized bodies now catalogued, while Pluto itself is just one of a collection of similar sized objects. The talk will classify the members of the outer solar system, what research is currently taking place, speculate on future discoveries, and detail why Pluto was demoted from planet status."

7. Take your classroom into space, with astronaut Andre Kuipers: When liquids and bubbles are in space, odd things begin to happen. Astronaut André Kuipers from the European Space Agency (ESA) is taking schools across Europe on a microgravity waltz to learn what is behind seemingly simple phenomena such as convection and foams. Space oddities on the International Space Station will help thousands of schoolchildren to realise that the consequences of the laws of physics running our Universe can be complex – and on Earth they are not the same as in the Station's weightlessness. Armed with two ESA educational experiments during his PromISSe mission, André is inviting students aged 10 to 14 to share his scientific adventure. (IAA members will recall the superb event we had with Andre about 10 years ago in Stranmillis College - an unforgettable evening!)
