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.

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.
