Podcast #31: Clem Unger talks about OSIRIS-REx

Welcome to the 31st episode of the Urban Astronomer Podcast. This episode features an interview with Clem Unger, an ambassador for the OSIRIS-REx mission who lives in Australia. This is followed by the next part of our series on the evolution of stars, taking us one step closer on our journey to seeing where supernovae come from. Clem Unger A few weeks back, I spoke to Clem Unger, who lives in Australia and serves in his spare time in the ambassador program for the OSIRIS-REx mission, which will be arriving at the asteroid Bennu in December this year, although it begins its approach in just over a month from the time this episode airs. Clem is an amateur astronomer like myself, and I'm hoping to bring him back to the show for future episodes. Stellar Evolution: Different sizes This is a short segment this week. We revise a few points behind how those big diffuse gas clouds collapse into stars. This leads us to understand how the size of the cloud leads directly to the size of the newly created star. Different size stars burn in different ways, and fit into distinct types. We look specifically at Brown Dwarfs, Red Dwarfs and Yellow Dwarfs.   Links OSIRIS-REx NASA
