I am an astronomer and scholar whose research focuses on protoplanetary disks around young stars—the birthplaces of planets. Planets orbiting stars other than the Sun are called exoplanets, and I collaborate with scientists around the world to learn about their origins. Most of the thousands of exoplanets discovered so far are unlike anything we’ve seen in our own Solar System. The more I learn about distant stars and diverse exoplanets, the more I appreciate our home here on planet Earth. Earth is the only planet we know of that hosts vast oceans and forests full of life. Earth is probably the only planet in the Universe with soft serve ice cream. As an astronomer, I am curious about the many social and ethical implications of humanity’s exploration of space. From journeys to the Moon, Mars, and possibly beyond, what does our leaving of Earth signify? Who benefits and who is harmed when we launch new space missions or establish colonies on other planets? Is it ethical for humanity to seek out new worlds to call home? As a college fellow I am excited to explore these ideas alongside students who bring their own perspectives and experiences to the classroom.
