Space Nuts Episode 471: HERA's Journey and the Light of Healing

Join Andrew Dunkley and Professor Fred Watson in this enlightening episode of Space Nuts, where they explore the latest developments in Space exploration and the fascinating role of light in both astronomy and human healing.

Episode Highlights:

- HERA Mission Milestones : Discover the latest updates on the HERA mission, including critical trajectory corrections and its upcoming Mars gravity assist. Learn about its objectives, including a close encounter with Mars' moon Deimos, and its ultimate goal of orbiting the asteroid Didymos.

- Black Hole Light Echoes : Delve into the intriguing concept of black hole light echoes and how light can be bent by gravity to create multiple observations of the same event. Understand the potential of using Very Long Baseline Interferometry to study these phenomena and what it could reveal about accretion discs.

- Healing with Light: Explore the historical and modern uses of light in medicine, from ancient sun worship to contemporary phototherapy treatments. Hear Andrew's personal experience with radiation therapy and the importance of regular health checks.
