Aparna Venkatesan, Ph.D.
Who Owns the Night Sky?
Thursday, September 12
7pm
FREE & OPEN TO THE PUBLIC
Space exploration is increasingly privatized, from Earth's orbital space to the Moon and beyond. This has led to increasing congestion and environmental degradation of low-Earth orbits. Along with dramatic rises in ground-based light pollution, this has caused brightening night skies worldwide. The loss of dark skies and increasing space debris are already affecting astronomical observations as well as broader constituencies across humanity and the health of many ecosystems. This includes growing impacts on the rights of future generations, and on Indigenous communities, their scientific-cultural practices and sky traditions. The environment of our shared skies represents our shared origin story grounded in language, science, storytelling, sacred relationship, and interdependent health, needing advocacy and protection more than ever. Teznie Pugh, who will in attendance for the Q&A, is the Superintendent of the University of Texas at Austin McDonald Observatory. Dr. Pugh works closely with local, regional, and national representatives and organizations on limiting artificial light at night and was a driving force behind the founding of the Greater Big Bend International Dark Sky Reserve, the world's largest certified International Dark Sky Place to date spanning over 15,000 square miles in Texas and Mexico.
Aparna Venkatesan is an astronomer in the Department of Physics and Astronomy at the University of San Francisco, and co-Director of USF's Tracy Seeley Center for Teaching Excellence. She works on studies of the first stars and quasars in the universe, and on numerous cultural astronomy and space policy projects. She serves as co-Chair of the American Astronomical Society's Committee to Protect Astronomy and the Space Environment (COMPASSE). Aparna has been recognized internationally for her research and diversity/inclusion leadership, featured widely in the media, and received numerous prizes and awards. She recently coined the term noctalgia with Dr. John Barentine to express “sky grief” for the accelerating loss of the home environment of our shared skies.
