Weekend Variety Wireless - Hour 1 - 24/11/18

First up, Science Report with Emily Parke. Why is wombat poo square and what are dogs really thinking? Then, Astronomy with Grant Christie. Lots of great links to videos this week, especially fascinating a huge young crater just discovered under the Greenland ice. The unexpected trajectory of visiting interstellar thing Oumuamua. Our Milky Ways supermassive black hole. This visual depiction is much more than it may seem. Its not an artists impression but the culmination of enormous computing power and the best known visualisation of whats really happening. The INSIGHT Mars lander is expected to touch down Tuesday 9am NZT. A huge crater found under the Greenland ice may explain some weird stuff from pre-history. WOW. Weekend Variety Wireless with Graeme Hill, 8pm - midnight Saturdays and Sundays, on RadioLIVE and streaming live to the Rova app on Android and iPhone.
