Strangers and giants: Uranus and Neptune

The worlds of the giant planets Jupiter, Saturn, Uranus and Neptune are full of superlatives. Apart from the Sun they are the largest and most massive objects in our Solar System and their influence is felt over enormous distances. The rings and numerous moons around the giant planets lead some people to think of them as miniature solar systems in their own right. Giant planets also have intense magnetic fields and are highly efficient charged particle accelerators which results in spectacular aurorae (northern lights). To mark the 25th anniversary of the first flyby of Uranus by Voyager 2, this talk will take you on a cruise of the giant planets before focusing on Uranus and Neptune to show how much we still don't know about these distant bodies. The talk will conclude with an overview of upcoming missions to the outer planets.

About Chris Arridge

Chris Arridge is a planetary scientist at Mullard Space Science Laboratory, University College London. His professional work is focused on the Cassini-Huygens mission to Saturn and future European missions to the outer planets. His scientific research involves the study of magnetic fields and charged particles around giant planets. Originally from Hull, he studied at the University of Wales Aberystwyth, the University of Cambridge, and Imperial College London where he gained his PhD studying some of the first measurements made by the Cassini orbiter at Saturn. Chris is also active in the engagement of young people in science, mathematics and engineering.
