When the sun came up on May 28 in the year 585 BCE, the Medes and Lydians were still at war. They had been at each other’s throats for years, and it looked like there was no end in sight for their conflict. But something extraordinary happened on the battlefield that day, which changed everything. This episode also features an interview with Dr. Fred Espenak, an astrophysicist, and scientist emeritus at NASA's Goddard Space Flight Center.
