Lecture Weds 29th Nov - Dr Stuart Sim (QUB) - "Anti-matter in the Milky Way"

Dr Stuart Sim

The 'missing antimatter' problem is one of the major mysteries in our understanding of the universe. All versions of the Big Bang model indicate that ordinary matter and antimatter should have formed in equal quantities, and then mutually annihilated each other. The very fact that we are here, in a universe made almost exclusively of ordinary matter (ignoring Dark Matter and Dark Energy in this context), indicates that there's something missing in the theory! But antimatter does exist, as occasionally single antimatter particles are created by cosmic rays in our atmosphere; and it has been created in the lab in very small quantities, so it's real.

Lecture Weds 15th Nov – Dr David Lisk, ‘Astronomical Spectroscopy for Amateurs’

Dr David Lisk

Spectroscopy is a technique used to measure the spectrum of electromagnetic radiation and includes the visible light which radiates from stars and hot celestial objects.

This talk explains the terms used in astro-spectroscopy and examines how, using technology now available to the amateur astronomer, scientific measurements of a star’s type, temperature and chemical composition can be made.
