Dark skies: why we need to preserve them

Open Night on 25 May 2019
“Dark skies: why we need to preserve them”


Members of the public are welcome to an Open Night at the SAAO in Cape Town on 25 May 2019, starting at 20h00. Dr. Ramotholo Sefako (SAAO) will present a talk titled Dark skies: why we need to preserve them. This will be followed by a tour of the site and (weather permitting) star gazing.

Summary of the talk

Dark skies are an important natural resource that we need for observational optical astronomy research and a balanced life on Earth. Light pollution is the main enemy of our dark skies. Dr. Sefako will discuss some of the threats of light pollution not only to astronomy, but also to human health and wildlife.

He will also discuss SAAO-NRF efforts in partnership with Astronomy Management Authority within the Department of Science and Technology to, among others, protect the SA Astronomical Observatory observing station near Sutherland against light pollution, thereby contributing to preserving one of our most important natural resources in South Africa, dark skies.


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.
