Prof Michele Dougherty, a leading space physicist who was a researcher for the Nasa Cassini mission, has been awarded the 350-year-old honorary title.

As an investigator on two major space missions, Dougherty has played a role in discoveries in the solar system including the revelation that jets of water vapour shoot out from one of Saturn's moons, Enceladus, meaning it may be able to support life.

Dougherty said she was "absolutely delighted" with her appointment. She added: "As a young child I never thought I'd end up working on planetary spacecraft missions and science, so I can't quite believe I'm taking on this position. I look forward to engaging the general public in how exciting astronomy is, and how important it and its outcomes are to our everyday life."

The role of astronomer royal was created in 1675, with the aim of discovering how to determine longitude at sea when out of sight of land.

The outgoing astronomer royal, Martin Rees, is retiring from the role.
