Was humanity hit with a comet 12,900 years ago? Will we be hit again in a few decades? In today’s episode, we discuss the highly debated argument that a comet struck the Earth in our recent past, causing the global cooling observed during the period known as the Younger Dryas (12,900 to 11,700 years ago). We also discuss the near-Earth asteroid Apophis and its upcoming close encounters with our world that, although unlikely to impact, could enable some opportunistic science. And of course, we give a shoutout to the Perseverance Rover, which just executed an impressive landing on Mars!
