Monthly Talks on Astronomical Topics of Interest

Monthly Public Talks

Our popular monthly talks are for members and the public to learn about some aspects of astronomy. These talks are aimed at ‘middle of the road’ level so the talk will appeal to members of the public with no prior knowledge, newcomers as well as those who have been interested in the subject for a number of years.

Topics from imaging the night sky, through to Cosmology, we invite speakers from all over the UK and the World.

We make a small charge on the door of £3.00 to cover our expenses

Our local venue:

Clanfield Memorial Hall,
South Lane,

Earth’s aurora and magnetosphere

A talk by Dr Robert C Fear

Cost: Non-members: £3

The Earth’s aurora, or northern (and southern) lights are one of the most beautiful manifestations of the Sun’s influence on the Earth. They arise as a result of the interaction between the solar wind, the magnetosphere (the region of space surrounding Earth), and the upper atmosphere. Our understanding of both the aurora and magnetosphere has transformed from humble beginnings in the early 20th century to the modern day, yet many questions remain and they are both active topics of research both for those interested in pure scientific research (“How does our Solar System work?”) and the application of this field on modern technology (space weather).

Exoplanets: where are our alien neighbours?

A talk by Professor Don Pollacco

Cost: Non-members: £3

We live at a time where the discovery and characterisation of exoplanets seems routine. Here we will review the current state of the art and show the limitations of the data and the claims that are made from it. We will discuss the present population of habitual zone planets looking for the fabled earth 2. Finally, we will look ahead at new experiments and in particular the ESA M3 Mission PLATO which is designed to discover habitable zone terrestrial planets in the next decade

The Star of Bethlehem

A talk by Mark Kidger

Cost: Non-members £3

Dr. Kidger begins with the stories of early Christians, comparing Matthew's tale of the Star and the three Magi who followed it to Bethlehem with lesser-known accounts excluded from the Bible. Crucially, Dr. Kidger follows the latest biblical scholarship in placing Christ's birth between 7 and 5 B.C., which leads him to reject various phenomena that other scientists have proposed as the Star. In clear, colorful prose, he then leads us through the arguments for and against the remaining astronomical candidates. Could the Star have been Venus? What about a meteor or a rare type of meteor shower? Could it have been Halley's Comet, as featured in Giotto's famous painting of the Nativity? Or, as he suspects, was the Star a combination of events--a nova recorded in ancient Chinese and Korean manuscripts preceded by a series of other events, including an unusual triple conjunction of planets?
