This week Cariad talks to astrophysicist and planetary scientist at MIT, Sara Seager. Sara is the author of the beautiful memoir, The Smallest Lights in the Universe. Sara spoke to me about the death of her husband from cancer when she was just forty. As ever we talk grief, exoplanets + the emotional debt of grief. You can follow Sara on twitter @ProfSaraSeager, her book is published by Penguin Random House and is available to buy now. You can follow the Griefcast on Twitter + Instagram @thegriefcast Griefcast is hosted by Cariad Lloyd, edited by Kate Holland, recorded at Whistledown Studios (or Cariad's living room in lockdown), artwork is by Jayde Perkin and the music is provided by The Glue Ensemble.
