This week, McDonald Observatory and numerous partners join in celebrating the first anniversary of the Greater Big Bend International Dark Sky Reserve. Covering more than 15,000 square miles in Texas and Mexico, the reserve is the largest dark sky place in the world certified by the International Dark-Sky Association (IDA). This achievement builds on a rich history of efforts to preserve the night skies in the region.

Dark skies are crucial for preserving the night sky’s natural beauty and reducing the negative impacts of light pollution on scientific observations, human health, wildlife, and the environment.
