A green light shot across Minnesota's sky. An MPR News reporter saw it and sought to learn more

This past Saturday, people across northern Minnesota and Wisconsin saw a long flash of sparkling white and green light trail across the night sky. People captured it on video and it went viral on social media. But no one was exactly sure what it was. Maybe a meteor? A comet? Santa doing a test run with Rudolph? MPR News Duluth reporter Dan Kraker made it his mission to find out after seeing the spectacle himself. He joined Minnesota Now host Nina Moini to talk about what he learned about the so-called “space junk.”
