Has anyone ever told you not to stare at the Sun

Well, in this episode, Caitlin is disregarding that advice and looking directly at the focal point of our solar system. We travel through the Sun's many layers down to it's core (which reaches up to 27 million degrees Fahrenheit!) as she explains everything from how light travels through the Sun to what creates Sunspots.

Welcome to Scratching the Surface with Caitlin Ahrens, the Pluto Manager at the Center for Space and Planetary Science.

Most of us experience space through pictures and maps viewed from the comfort of our own home. But it takes a lot of work to deliver those images from the heavens to our fingertips. 

In this episode, Caitlin talks about the need for more space missions to develop in-depth maps that give us a better understanding of our solar system and beyond.
