Today we’re tackling something we’ve wanted to talk about for a long time (which is relative, because time and space lose all meaning there). They’re incredibly dense, super cool, and mind-bendingly-mysterious -- BLACK HOLES! But how do you imagine – let alone study—the unseeable? And seriously—what happened at the end of “Interstellar?”

The concept of black holes isn’t new—scientists first theorized their existence in the early 20th century. But in the last few years our knowledge of black holes has expanded – from confirmation of a supermassive black hole at the center of the Milky Way (it really ties the galaxy together) to the first-ever image of a black hole captured by the Event Horizon Telescope. We’re now making direct observations that prove their existence. And just yesterday(!) scientists released an image of a black hole in polarized light, with signs of magnetic fields around the event horizon. And if you don’t understand what that means, you’re not alone!! We’re all on this magic school bus of discovery together – come abroad, it’s going to be a wild ride!
