Jonti Horner

Professor (Astrophysics), University of Southern Queensland

I'm an astronomer and astrobiologist based at the University of Southern Queensland, in Toowoomba, Queensland.

I first became interested in astronomy as a five-year-old, as a result of viewing an accidentally recorded episode of the Sky at Night.

I've always been particularly interested in our Solar system, especially the small objects therein - the comets, asteroids and meteors.

In recent years, I've been expanding my research to include astrobiology and the search for, and study of, exoplanets.
