概要
In this episode of Astrophysics for All, I speak with Dr Caroline Foster, an observational astronomer at UNSW Sydney who studies how galaxies form, grow, and evolve over billions of years.
We explore how astronomers use light to measure the motions and chemistry of stars, how galaxies grow through mergers and star formation, and why some galaxies gradually stop rotating as they age. Dr Foster also explains how globular clusters—ancient, tightly packed groups of stars—act like cosmic fossils that help astronomers uncover the hidden histories of galaxies.
Dr Foster shares how she first became interested in physics and offers advice for students who want to pursue astronomy, highlighting curiosity, mathematics, and the excitement of exploring the biggest questions about the universe.
