The Skyentists

019 - Planet Up!


Listen Later

For the first episode of The Skyentists in 2019 astronomers Ángel López-Sánchez and Kirsten Banks jump into the exciting field of finding planets around other stars. They provide a summary of the observational techniques used by astronomers to discover exoplanets, emphasizing the two main methods: the transit (or mini-eclipses) method and the radial velocity or doppler shift (or "wobbly") method. They also characterize the general properties of the almost 4000 exoplanets already discovered and provide a list of the ~20 most exciting exoplanets (some of them seem to be taken from "Star Wars"). In "Space News" Kristen summarizes Space-X launches in 2018 and their plans for 2019, while Ángel talks about the recent research of 20 protoplanetary disks using the radio-interferometry ALMA. We answer some questions received for feedback (thanks!) and use the brightest star of the night sky, Sirius, for our "What's Up" section. More in 2 weeks!
