The life and death of stars
Listen to the latest episode of Radio Astronomy, the podcast from the makers of BBC Sky at Night Magazine.
This episode we reveal how stars are born, evolve and die, and discover that a star's mass determines its ultimate fate.
Plus, we speak to astronomer Emily Cannon about her research into the dimming of Betelgeuse, a red giant star that forms part of the Orion constellation. Could it be about to go supernova?
Iain Todd is BBC Sky at Night Magazine's Content Editor. He fell in love with the night sky when he caught his first glimpse of Orion, aged 10.
