Virtual Event

Everyone is warmly invited to join us for this year’s Astronomy For All Lecture.

The lecture will be introduced Vice-Principal Dr Rebecca Surender and delivered by Associate Fellow Charles Barclay.

This illustrated talk will highlight the pivotal and unsung role played by women in astronomy and astrophysics.

It has been 100 years since the death of Henrietta Leavitt, the discoverer of the Period-Luminosity law for Cepheid variable stars, from which Edwin Hubble was able to measure the scale and expansion of the Universe. The talk will review the importance of Leavitt’s work and also single out three other women, whose 20th Century contributions, in their respective fields, have been critical to the development of the whole subject.

The Astronomy For All Lecture Series was started by Charles in 2006 as a way of strengthening and reinforcing the link between Green Templeton, home of the Radcliffe Observatory, and astronomy and the Oxford Astrophysics Department, in particular.
