SAAO Cape Town Open Night

Nov 26 @ 8:00 pm - 10:00 pm

This week’s talk: Christian Hettlage

The SAAO Open Nights in Cape Town take place on the second and fourth Saturday of every month at 20:00.

All Open Nights will start with a presentation on topics of astronomy or physics. Then, visitors will be given an introduction to the historic McClean telescope, the observatory museum, and the library. If the weather is clear, there will be a chance for stargazing using telescopes set up for the night.

Please email enquiries@saao.ac.za if you have any queries regarding bookings and tours for Cape Town Open Nights.


Christian is a software engineer at the SAAO, developing tools for the Southern African Large Telescope (SALT). He came to Cape Town in 2006 after completing his PhD in Germany.

Talk Abstract:

A Journey without Return: Black Holes

Black Holes, objects from which nothing can escape, are one of the most fascinating predictions of Einstein’s Theory of General Relativity, and they feature in many science fiction stories. This presentation explains the physics behind Black Holes, where (and how) to find them in the universe, how radio telescopes managed to take an “image” of a Black Hole just a few years ago, and why Black Holes are connected to an Italian pasta dish.
