Bursts, bangs and things that go bump in the night – transient astronomy, by Professor Dame Jocelyn Bell Burnell – ONLINE

August 3 @ 7:15 pm
Jocelyn Bell Burnell

Jocelyn Bell Burnell We are honoured that Professor Dame Jocelyn Bell Burnell is finding time in her very busy diary to deliver a talk to Members, online via our usual Zoom platform. With improved technology astronomers are now able to observe things that rapidly change their brightness. Opening up this 'transient' domain has revealed a wealth of amazing phenomena which will be introduced here. Jocelyn Bell Burnell inadvertently discovered pulsars as a graduate student in radio astronomy in Cambridge, opening up a…

Solar flares – the most powerful explosions in the Solar System, by Professor Philippa Browning – ONLINE

October 19 @ 7:15 pm
Professor Philippa Browning

Professor Philippa Browning Solar flares are powerful “explosions” in the Sun’s atmosphere, the corona. They are caused by a rapid release of the energy stored in the strong magnetic field of the corona – the magnetic field lines break in a process known as magnetic reconnection. This heats the gas to temperatures of tens of millions of degrees and creates beams of very high-energy charged particles. The particles and electromagnetic radiation from flares can have significant effects on the Earth…
