This week, we present two stories about dark moments in science. Part 1: Astrophysicist Jesse Shanahan tries to uncover the mysteries behind both the black holes she studies and her own chronic pain. Part 2: Comedian Sarah Pearl checks into a psychiatric hospital after having suicidal thoughts. Jesse Shanahan is a science writer and astrophysicist, currently serving as a Coordinating Committee member in the Working Group on Accessibility and Disability that she co-founded for the American Astronomical Society. Her writing can be found in Science, Astronomy Magazine, and Forbes amongst others. In addition to organizing STEM outreach in local elementary schools, she works on behalf of disabled scientists to facilitate accessibility and accommodations in STEM. Outside of her research on supermassive black holes, she spends her days wrangling a very high energy Border Collie named Hubble and playing way too many video games. Follow her @enceladosaurus.   Born and raised in St. Louis, Sarah Pearl is an up-and-coming comedian, musician, and storyteller. She's performed throughout the Midwest, most notably at Laugh Factory Chicago, Helium Comedy Club, and one time, a back porch without a coat during winter. Her honest and sardonic style has been referred to as, "kind of sad, but really funny." Sarah will be debuting the story of her experience with mental illness and she hopes the storytelling class she took when she was eight pays off.
