Great Weather For Observing The Mercury Transit From Queen’s University Belfast
On Monday May 9, Mercury transited the Sun. During the day the Astrophysics Research Centre of Queen’s University Belfast, together with the Irish Astronomical Association, set up telescopes equipped with special solar filters in front of the Lanyon Building to allow the general public to take a close-up look at this unique event.
During the day, more than 500 people took the opportunity to see our smallest planet journey across the face of the Sun.
In the afternoon several school groups attended our special workshops where they were treated to a virtual tour of the Solar System, got a live view of the transit of Mercury through the telescopes and did some real science by calculating the size of Mercury from their observations.
In the evening Professor Patrick Brady gave the Michael West Lecture entitled Einstein's Gravity: from the transit of Mercury to the detection of gravitational waves. More than 110 people attended this captivating lecture on probably the hottest topic in astronomy at the moment.
Dr. Ernst de Mooij gave school pupils a guided tour of our solar-system
Safety first. Pupils from St. Dominic's Grammar School made sure to wear solar glasses when viewing the Sun.

Using their telescope observations pupils were able to measure the relative diameters of the Sun and Mercury. Dr. David Young helped to show pupils how to use these relative measurements to calculate the true physical diameter of the rocky planet.
