Welcome to episode 29 of the Urban Astronomer podcast. As you know by now, we mainly feature interviews with people connected to South African astronomy. But since we had no guests lined up for this episode, we decided it was time to keep a promise we'd made a month ago to listener Andrew Botteril, from KwaZulu-Natal province in South Africa. Andrew is a fan of the show and had asked that we feature a little more basic science, explaining some of the physics behind the astronomy. So, we're starting a series on stellar evolution. This episode looks at the behaviour of gas molecules, and how this causes vast clouds of hydrogen floating in space to turn into stars. The final episode will discuss the ultraviolent supernova explosions that mark the end of life of the very biggest stars, and all the rest will cover the journey between.
