Astrophiz 22: Parkes Dish Chases Gravity Waves, Aliens & FRBs - Nadezhda on Stellar Evolution
b'Astrophiz 22 is out now on Soundcloud or subscribe in iTunes\\n\\nPart II: The Parkes \\u2018Dish\\u2019 interrogates pulsars to expose gravity waves. We interview Operations Scientist John Sarkissian at the CSIRO Parkes Radio Observatory. He explains how the \\u2018Spider Dipoles\\u2019 that make up the Murchison Widefield Array in remote Western Australia contribute to SKA, how Parkes chase down gravity waves and has detected most of the world\\u2019s FRBs (fast radio bursts of unknown origin), after being distracted by \\u2018perytons\\u2019 and microwave ovens. And yes, \\u2018The Dish\\u2019 is searching for Extraterrestrial Intelligence in the international SETI \\u2018Breakthrough Listen\\u2019 project. We\\u2019re not saying they\\u2019re searching for Aliens \\u2026.. but Aliens!\\n\\nDr Nadezhda in Part I of Stellar Evolution explains how the mass of a star determines its evolutionary path, and next week we will look at the Hetsprung-Russell Diagram\\n\\n\\u201cWhat\\u201ds Up in the Sky this Week\\u201d for Northern Hemisphere observers and astrophotographers, and for Southern Hemisphere Listeners, December is the best time to see the Large Magellanic Cloud and the Small Magellanic Cloud. We also expose Procyon and curse the moon for demolishing the Geminids Meteor Shower\\n\\nIn the News:\\n1. The Spiderweb galaxy \\u20282. Imaging a Black Hole Event Horizon \\u20283. ICRAR tells us the Universe is slowly becoming less energetic (Well, who isn\\u2019t ;)'
