On 27th July 2017, the RoI Minister John Halligan switched on I-LOFAR telescope, the largest radio telescope in the world, at Birr Castle in Co. Offaly.

The Armagh Observatory and Planetarium is a member of the 8 institutions across the island of Ireland that came together to build I-LOFAR.

The International LOFAR (LOw Frequency ARray) Telescope is a €150 million network of radio telescopes distributed across Europe.

I-LOFAR, is located at Birr, Co Offaly adjacent to the historic Leviathan telescope, which was built by the 3rd Earl of Rosse in 1845 and was the largest optical telescope in the world until 1917.  This revives the historic links between Armagh, Dunsink and Birr in the 19th century, which frequently saw Armagh Director Romney Robinson at Birr Castle using the Leviathan telescope.

Profesor Gallagher, Head of the I-LOFAR Collaboration and Associate Dean of Research at Trinity, said “The Irish LOFAR radio telescope opens up a new era of astronomical research in Ireland and connects us to the leading network of radio telescopes in Europe. It will be used to study the early Universe, detect exploding stars, search for new planets and understand the effects of the Sun on the Earth.The huge volumes of data that the radio telescope will produce will requires us to develop new software and data analytics techniques to process and understand the data. I-LOFAR really is a test-bed for big data in Ireland.
