8th January – IAA Lecture – “The Origin of the Elements: Stars, Supernovae and the Big Bang”, by Dr Stuart Sim, QUB.

Supernovae are just about the biggest explosions in the universe, and certainly the biggest that we are ever likely to see. Not only that, but they create all the elements above iron in the periodic table, many of which, such as nickel, zinc, selenium, and iodine, are essential for human life. They are also the key element in the 'distance ladder' used in large scale astrophysics and cosmology, as they are used to measure the distance to distant galaxies and galaxy clusters.

It's from studying distant supernovae that scientists now believe that the expansion of the universe is speeding up, leading to the theory of 'dark energy'. In other words, it's hard to think of any other single phenomena that's more important in modern astrophysics and cosmology.

This lecture will be a fascinating account of one of the cutting edge areas of modern astronomy.
The lecture is free and open to all, including free refreshments. Venue: the Bell Lecture Theatre, Physics Building, Queen's University, Belfast, at 7.30 p.m.
Thanks to the Astrophysics Research Centre, QUB, for help in hosting these lectures.
