Then I worked at the Harvard-Smithsonian Center for Astrophysics, Cambridge, USA for a few years. There I studied some planets and stars as well as the Sun. I did some observations of Io, one of the moons of Jupiter.
Io has a ring of plasma around it, which is the part I studied.
When did you first get interested in astronomy?
I've been interested in astronomy since I was about 8 or 9. At school I found that my main talents were in maths and science and I realised that here was a chance of becoming an astronomer. Although I enjoy studying the Sun, I'm also very interested in other astrophysical objects, planets and other stars.
