What astronauts' extraordinary experiences of awe and humility teach us about humanity. What is it like to stand in the shadow of Earth and the Moon and look out at the vastness of the Milky Way? To confront a view so grand it cannot be reproduced in a photo? These are the questions space anthropologist Deana L. Weibel asked as she interviewed astronauts and others in the space community. What they told her was not just surprising but also deeply moving. When gazing into star fields not fully visible from Earth, these astronauts experienced a profound sense of humility that fundamentally transformed their understanding of humanity. Welcome to the ultraview effect.The ultraview effect expands on the classic "overview effect." Comparing spacefarers to religious pilgrims, Weibel suggests that this experience of deep humility is a generative reaction to awe, which inspires exploration and adventure. When facing the vastness of the universe, acknowledging our monumental ignorance is what drives our will to discover. A fascinating dive into science, cognition, and spirituality,The Ultraview Effectdraws from astronauts' own accounts to make the case that continued human space exploration is not only a scientifically essential endeavor but also a culturally enriching one.
