Dr. Steven Barrett - as a Senior Research Fellow in the Department of Physics, my research interests span all aspects of imaging, image processing and image analysis. This includes medical imaging (biophysics), scanning probe microscopy of atoms and molecules (nanophysics), microscopy of earth materials (geophysics) and astrophotography.
Gaia has spent a decade mapping the Milky Way by making three trillion observations of two billion stars. How did it do this and what will we learn when all the data is analysed?
From 27 July 2014 to 15 January 2025, Gaia has made more than three trillion observations of two billion stars and other objects throughout our Milky Way galaxy and beyond, mapping their motions, luminosity, temperature and composition. Gaia's extraordinarily precise three-dimensional map will provide the data needed to tackle an enormous range of important questions related to the origin, structure and evolutionary history of our galaxy.
