Guildford Astronomical Society


The 2020-2021 season is a bit different due to the ongoing Covid-19 issues & being able to keep socially distant.
The University Lecture theatres are not accessible, so we are planning Zoom talks for our members.
Joining details of each meeting will be sent out prior to each talk.

Below are our current guest speakers.

The 2020-2021 Session

DateTalk/Presentation TitleSpeaker
3 Sep 2020A Zoom talk:- Crowd and the CosmosProf. Chris Lintott
1 Oct 2020A Zoom talk: Recent findings of a possible neutron star in Supernova 1987A.Dr Mikako Matsuura
5 Nov 2020A Zoom talk: Radio Astronomy for Amateurs

It often surprises amateur astronomers that it is possible to observe at radio wavelengths without needing a huge Jodrell Bank sized dish.
This talk will describe some of the observations which can be undertaken by amateur observers, the equipment needed and how to get started.
Projects can start with solar observations which can be made indoors with simple equipment and can progress to more complex outdoor antennas.
Radio astronomy is not limited by light pollution and weather and can be an interesting sideline to optical observations.

4 Feb 2021A Zoom talk: Supernova Neutrinos

A core-collapse supernova - the explosive death of a massive star - is one of the most spectacular events in astronomy. Supernova 1987A was visible to the naked eye, despite being 160000 light years away in the Magellanic Cloud; the supernova of 1034, which created the Crab Nebula, was visible in daylight for 23 days and at night for nearly two years. Yet these spectacular light shows involve only 1% of the energy released by the exploding star: the remaining 99% is emitted in the form of neutrinos. This was verified in 1987 by the detection of about 20 neutrinos from SN 1987A, but if a core-collapse supernova were to occur in our own Galaxy, our modern - much larger - neutrino detectors would see thousands of neutrinos.
In this talk I wll explain why supernovae produce neutrinos (and why neutrinos are necessary to produce supernovae), how we detect them, and what we might learn from the next Galactic supernova.
