"Exploration of the gas giant planets"

By Dr. Caitriona Jackman, DIAS

7PM Monday 8th of February.


As a non-profit organisation we are heavily dependent on your generosity at all times but especially in these challenging times. Your donations help us to keep your interest in astronomy and space alive as well as presenting you with lots of interesting and up to date information and events.

Another way you can offer support is by buying a magazine in the Lecture Booking Form below.

If you would like to view the lecture but are not in a position to donate please email our admin team who will add you to the lecture admittance list.





This lecture will be presented on the ZOOM platform in line with Public Health Guidelines.

Typically a gas giant is a large planet composed of gases to large extent with a rocky core. The gases are diverse but are mainly hydrogen and helium. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. The four large planets are in the outer part of the solar system beyond Mars. Uranus and Neptune are much smaller that Jupiter and Saturn, and both pairs of planets have different compositions.

In this lecture Dr. Jackman will provide the audience with plenty of fun facts about the amazing worlds of dynamic auroral displays, diverse moons, and mysterious atmospheres. She will also focus on some of the famous spacecraft including Cassini which spent 13 years exploring the Saturn system, and NASA's Juno which is currently in
orbit around Jupiter.





Dr Catriona Jackman is an Honorary Professor at the Dublin Institute of Advanced Studies and heads a group researching Planetary Magnetospheres.

Dr. Jackman obtained a BSc in Applied Physics from the University of Limerick in 2003 and a PhD in Planetary Physics from the University of Leicester in 2006. She has held research positions at Imperial College London, and two consecutive fellowships (Leverhulme Trust and Royal Astronomical Society) at University College London.

She moved to the University of Southampton in 2013, where she has held a Science and Technology Facilities Council (STFC) Ernest Rutherford Fellowship to study planetary and stellar magnetospheres. She is a Fellow at the Alan Turing Institute, the UK's National Institute for Data Science and Artificial Intelligence.

At the heart of her research is Space Plasma Physics in our solar system and beyond. She is an expert in planetary magnetospheres, the magnetic bubbles which surround magnetised planets. She has worked with data from missions including NASA's Cassini at Saturn, ESA's Cluster mission in orbit around Earth, NASA's Juno at Jupiter, and with data from the Hubble Space Telescope, and the Chandra X-ray Observatory.
