Exhibition Area

Would you like to touch a real meteorite? Spin the clouds of Neptune? Create your own solar system, or perhaps a black hole? Our recently refreshed exhibition area features all of that and more: the history of astronomy in Armagh, the Solar System, stars, galaxies… Our new Sensory Room provides a fun yet relaxing area for discovering the wonders of space, and the PufferSphere displays invite you to take your own tour of the planets or of the wonders of the Earth.


The Astropark is a scale model of the Universe, brought down to Earth in a beautiful natural setting. As you journey through the park you will get to interact with a scale model of the Solar System, the Universe, and more.

Data Visualisation Laboratory

The Data Visualisation Laboratory (DVL) brings the immersive experience of the planetarium dome to the researcher, providing tools for the visualisation of 3-dimensional data sets.  Our DVL combines a panoramic display, a large wall-screen and virtual reality (VR) to provide visualisations of multi-dimensional data sets.  On occasion public demonstrations are given where you can talk with an astronomer while going on tours of the cosmos using the panoramic display and the Digistar computer we use to generate our planetarium shows.
