Weekend Variety Wireless With Graeme Hill On Radiolive

This hour, Astronomer Dr Grant Christie joins Ryan Bradley in for RadioLIVE's Graeme Hill to talk the latest in astronomy news. First up Ryan and Grant take a look at Comet 21P that is currently visible in a good telescope in the pre dawn sky. Comet 21P / Giacobini-Zinner has developed a long tail that makes it a good sight for binoculars and sensitive cameras. Ryan and Grant take a look at why the SpaceX Lunar Tourists wont walk on the moon. Elon Musk has claimed his Big Falcon Rocket crew vehicle might one day land on the moon. But that's not in the cards for any missions in the foreseeable future. Then, when is a star not a star? Grant discusses how the line that separates stars from brown dwarfs may soon be clearer. Astronomers demonstrate that brown dwarfs can be more massive than astronomers previously thought. Grant and Ryan also explore Planets that are visible to the naked eye, the milky ways stars and much more. Weekend Variety Wireless with Ryan Bradley, in for Graeme Hill, 8pm - midnight Saturda
