Using the Universe as a natural laboratory from the centre of the Earth to the edges of the observable universe. The School is currently organised in two broad sections Astronomy & Astrophysics, and Geophysics.
The School has an active outreach programme seeking to communicate the excitement of its work to the public and in particular to schoolchildren. It runs the long-standing series of open nights at Dunsink Observatory, the Seismology in Schools Programme (Seismeolaíocht sa Scoil) and other outreach events such as the statutory public lecture series. It participates in science week and the BT Young Scientist exhibition, hosts the annual Hamilton walk, marks the summer solstice with the annual solar fest, and participates in Culture Night.
