Oxford University Space and Astronomy Society Lecture

Abstract

The traditional image of the astronomer peering through the eyepiece of a telescope and recording data is badly dated. Modern astronomy makes use not only of the light our eyes can perceive but radiation across the electromagnetic spectrum, from radio waves to gamma rays.  At the end of the 20th century, astronomers learned how to use pulsation modes of the Sun to deduce its internal structure.  Most amazingly, in the last few years we have been successful in detecting gravity in its radiant form, so that we can now see the darkest and most astonishing objects of all: black holes.  In this presentation, I will review these achievements and speculate on what the future will bring. 

Who is this event for?

This lecture is free to attend and is aimed at anyone with a passion for Maths and physics.
