Staring at galaxies with radio ‘eyes’

Open Night on 12 January 2019
“Staring at galaxies with radio ‘eyes’”


Members of the public are welcome to an Open Night at the SAAO in Cape Town on 12 January 2019, starting at 20h00. Dr. Jacinta Delhaize (University of Cape Town) will present a talk titled Staring at galaxies with radio ‘eyes’. This will be followed by a tour of the site and (weather permitting) star gazing.

Summary of the talk

Over the history of humanity, we have first used our own eyes, then built larger and larger telescopes to stare up at the skies. With these telescopes, we have learned about many of the wonders of the Universe. Not only have our telescopes grown bigger, they have also been constructed to ‘see’ different types of lights – not just the optical light we can see with our own eyes. We are currently in a golden age of radio astronomy, with South Africa being one of the countries leading the way.

The huge new MeerKAT telescope in the Karoo, and the upcoming Square Kilometre Array, are going to revolutionise our understanding of many aspects of astronomy. One of these aspects is the field of galaxy evolution. This is the study of how galaxies formed after the Big Bang and have changed throughout the history of the Universe. In her talk, Dr. Delhaize will explain how we know what we already know about galaxy evolution and what we hope to learn in the future with the next generation of radio telescopes.


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.
