Is it really darkest before the dawn? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice explore how light, ~heat~, and our daily temperatures work. What is the hottest time of day? Why isn’t it when the sun is at its highest in the sky? We break down earth, the atmosphere, and where energy gets absorbed. Why is it so cold up high in an airplane? Or in a desert at night? Find out about deserts and what makes their temperature shifts so extreme. What’s the coldest time of the day? The hottest month of summer? Plus, find out when Celsius and Fahrenheit equal each other, all on another StarTalk explainer!
