Astrophysics

Astrophysics is the application of the principles of physics to the study of astronomical objects and the universe as a whole. It asks how stars form, live, and die, what lies at the hearts of galaxies, how the solar system came to be, and what the large-scale structure and ultimate fate of the universe are. The discipline spans the solar system, gas giants and terrestrial worlds, red giants, white dwarfs, neutron stars, quasars, cosmological questions about dark matter and dark energy, and the earliest moments of the universe.

It draws on quantum mechanics, relativity, thermodynamics, and electromagnetism to build models that can be tested against observation.

At Aberystwyth University, this three-year full-time degree incorporates the broad disciplines of astronomy as described on the programme, engaging with cosmology and galactic astronomy, the solar system, stellar evolution, and exotic objects such as neutron stars and quasars. You will build a rigorous foundation in physics and mathematics alongside the observational and computational skills that modern astrophysics research demands, developing the analytical tools to engage seriously with some of the biggest questions in science.

Astrophysics graduates are well equipped for careers that require strong quantitative and analytical skills alongside scientific rigour. Many go on to postgraduate study in astrophysics, physics, or a related discipline, pursuing research careers in universities, observatories, and space agencies. Others move into data science, software engineering, finance, technology, and the civil service analytical fast stream, where the mathematical and problem-solving skills astrophysics training builds are highly valued.

Teaching is also a strong pathway, both in secondary schools and at university level, and science communication offers another route for those who want to share their understanding of the universe with wider audiences.
