More about the wonderful new digital dome and planetarium. Prof Michelle Cluver tells us about how this new high-tech facility at the Iziko Museum in Cape Town will be used for many different kinds of research. Visualising massive data sets is at the core of much of modern research, and this new digital dome puts us at the cutting edge of interpreting scientific data.

The Cape Town planetarium at the Iziko Museum has had a major renovation. Gone is the projector that used to rise from beneath the floor, to be replaced by something far more spectacular and wide-ranging in its appeal and what it can do. Here to tell us about the renovations is Prof Michelle Cluver from UWC. Go enjoy a fabulous show at the planetarium.

Find out about gravitational waves and the latest news about their detection from one of the visiting scientists at LIGO, Kai Staats. The announcement was made this week of a fourth detection, so it's great timing to speak to someone in the know. The Laser Interferometry Gravitational-wave Observatory has one of a handful of instruments on Earth that can detect these minute shifts in the very fabric of the universe. This is advanced science, and changes our understanding of the cosmos. Kai completed a MSc in Applied Mathematics at AIMS / UCT. How now works a freelance researcher and professional filmmaker. See link for his latest documentary about LIGO and gravitational waves.

Ancient and modern astronomers detect nova burst, and local scientists piece together the fragments of a puzzle providing evidence for the lifecycle of stars. It's important to keep old records!

Today marks the grand finale of the highly successful 20-year Cassini mission to Saturn, when the space probe enters the atmosphere to Saturn to end its days. To mark this occasion, Kechil recently interviewed South African Professor Michelle Doherty about Cassini's magnetometer, Saturn's moon Enceladus with its mighty plume of water, and about her role in the project. She touches on a future mission to Jupiter which we look forward to hearing more about in the future. For now it's farewell to Cassini.

Could Saturn's second moon harbour life? The Cassini spacecraft has detected that the ocean beneath Enceladus's icy crust is closer to the surface at the pole than previously thought, meaning that a future mission could probe this more directly and possibly find evidence for life forms.

In a galaxy far, far, far away. Kechil talks to Prof. Russ Taylor, UCT professor of astrology about the evolution of distant galaxies.

Find out about the local contribution to the amazing TRAPPIST-1 discovery. Rudi Kuhn, a SALT astronomer in Cape Town enthuses with Kechil about the view from the outer planet in this extraordinary solar system.

Don't miss Sunday's solar eclipse. It will be as spectacular as the latest news from NASA about the Trappist-1 solar system, where you would see multiple eclipses per day if you lived on one of the outer planets!
