Astrophiz 78: High Altitude UV Astronomy ~ Ryan Ridden Today we are speaking with Ryan Ridden, a PhD student at the Research School of Astronomy and Astrophysics at the Australian National University in Canberra. His research investigates cataclysmic events by launching UV telescopes attached to helium balloons high above the atmosphere! For observers and astrophotographers, in ‘What’s Up Doc’, Dr Ian ‘Astroblog’ Musgrave tells us what to look for in the morning, evening & night skies, and in ‘Ian’s Tangent’ he tells us about a cool Citizen Science experiment by Terry Lovejoy to use parallax to measure the distance from earth observers to the moon with remarkable accuracy using basic equipment and a little trigonometry. In the News: 1. Name That Moon! 12 Jovian moons were discovered in 2018, and the public have been invited to name five of them. Suggestions can be submitted until April 15, 2019, by sending a tweet to @JupiterLunacy, with written or video recorded reasons for the name chosen. Include the tag #NameJupitersMoons. 2. SKA News: The formation of the intergovernmental organisation for the SKA Observatory (SKAO) was signed off this week 3. Announcement time! @jdelhaize and @DanielCunnama are launching a podcast called The Cosmic Savannah!
