These observatories give us access to photons emitted by objects both in our local galactic neighborhood and in extremely distant galaxies, which we try to understand in conjunction with theoretical physical models and large scale computer simulations. Modern astronomy research is conducted through observations with large telescopes on high mountaintops or even in space. Cultures around the world and throughout human history have constructed knowledge about the universe via observations of the night sky. Astronomy is also one of the oldest and most universal scientific disciplines. It embraces such fundamental topics as the origin of the planets and moons of the solar system, the formation and evolution of stars and galaxies, the earliest moments of the universe’s history, the behaviour of matter in environments never experienced on earth, the conditions for life on earth and elsewhere, and in general, the influence of the universe on humankind’s thinking throughout the ages. The study of astronomy covers vastly different orders of magnitude in scale - from physics at the scale of a single atom all the way to physics on the scale of the size of the universe itself. Davis of all the sciences, is perhaps the most wide-ranging in its content and in its implications. (905) Counsellor/Undergrad Program Administrator
