Astronomical Sciences
Astronomical Sciences studies the vast universe beyond Earth, discovering objects and phenomena that do not exist on Earth or in the solar system, such as planets orbiting other stars, black holes and forms of mass and energy that cannot be seen even though they form 95% of the universe. To study these objects, astronomical sciences integrates the methods and knowledge of all the other sciences.

Other Programs to Consider
Earth Science
Earth Science is the discipline that studies our planet and all of its natural environments. Our program offers training in both critical streams of Earth Science: Resources & Tectonics and Earth, Climate & Life. Through our program, students become well equipped to understand the causes and consequences of radical shifts already underway in Earth’s climate system.
Geography (HBSc)
The Geography BSc offers a broad perspective on physical geography. In-depth studies include climatology, hydrology and ecosystems, with possible specialization in biogeochemistry, arctic regions, landscape ecology, natural resources and urban climate. The curriculum stresses the integrative nature of the discipline as well as the development of skills in geographical information analysis.
GeoSpatial Data Science
The GeoSpatial Data Science BSc offers an analytical perspective on geographical information. What you learn in the GeoSpatial Data Science program is applicable to employment in public and private sectors including public health and healthcare, urban transportation planning, natural resource management, and conservation agencies. In-depth studies — beyond basic geography — include mapping, spatial analysis, digital databases with specializations in modelling, statistical analysis and remote sensing.
