Hi everyone, I just enjoyed this talk by Joao Alves (tilde over the first o) from Radcliffe Institute at Harvard about the discovery of the Radcliffe Wave that puts to rest the Gould circle. It's ginormous. What do you think after listening? Is it a newly noticed arm? He is fun to listen to and for me explained the process and discovery very nicely. All the best, Shoshana Listen and watch here: https://www.youtube.com/watch?v=uZjiE81ofFM&feature=youtu.be
