Scott Jagow explores the wonders of extreme cold in this week’s "Three Good Things." From a bitter cold snap in Australia to the coldest known spots on Earth and in space—Antarctica’s Dome Fuji and the Boomerang Nebula—this episode dives deep into the science of freezing temperatures. Plus, a groundbreaking 3200-megapixel camera at the Rubin Observatory promises to map the night sky in unprecedented detail. And on Mars, NASA rovers face wild temperature swings as they hunt for clues of ancient life. Discover how cold can lead to some pretty cool science.
