The Visible and Invisible Inner Workings of Galaxies

Open Night on 23 March 2019
“The Visible and Invisible Inner Workings of Galaxies”


Members of the public are welcome to an Open Night at the SAAO in Cape Town on 23 March 2019, starting at 20h00. Dr. Moses Mogotsi (SAAO/SALT) will present a talk titled The Visible and Invisible Inner Workings of Galaxies. This will be followed by a tour of the site and (weather permitting) star gazing.

Summary of the talk

Galaxies are composed of more than just the stars we can see with our naked eye. The interstellar medium in galaxies is complex, requires studies at different wavelengths of light to understand and the different components give us information about the different properties and process that go on within galaxies.

The talk will take us on a journey from our home galaxy: The Milky Way all the way out to distant galaxies, showing their different components, and showing the kind of telescopes and parts of the electromagnetic spectrum that are used to study these components and galaxies to reveal what galaxies are made of, how they behave and evolve with time.


The Open Night will take place at the SAAO in Cape Town. The SAAO is located off Liesbeeck Parkway, next to the River Club.


Gates open at 19h30 and parking is available on site.
