Physics of the universe
UCD physicist Dr Lorraine Hanlon talks about the sun's vital role as a giver of life on earth and outlines how astronomers explore the many stars and galaxies in the universe.
In the clip, Lorraine refers to the 1:4 scale model of XMM-Newton, an ESA earth-orbiting satellite observatory, donated to University College Dublin by the European Space Authority, and on public display at UCD Science.
Physics is one of the subjects available through the Science programme at UCD. It is also possible to study Physics with Astronomy & Space Science. More at www.ucd.ie/science
