FAQ
Frequently Asked Questions
No. Astrophysics focuses on the physics of celestial objects (e.g., luminosity, mass, motion), while astrochemistry focuses specifically on their chemical composition and molecular processes.
They analyse data from telescopes (radio, infrared) to identify molecules in space, create laboratory experiments that simulate space conditions, and develop theoretical models of chemical reactions in astronomical environments.
It helps us understand the origin of the chemical elements, the formation of stars and planets, and the potential chemical precursors to life in the universe.
Yes, but usually as a specialisation within undergraduate degrees in chemistry, physics, or astronomy, or as a dedicated focus at postgraduate (MSc/PhD) level.
