Senate Resolution No. 451 recognizes the efforts of DarkSky Texas, a chapter of DarkSky International, in promoting the reduction of light pollution across the state. The organization advocates for better outdoor lighting practices to restore natural night skies, conserve energy, and enhance the well-being of both people and wildlife. DarkSky Texas educates the public about the negative impacts of excessive and poorly directed outdoor lighting, including its economic costs and its interference with astronomical research. The resolution highlights the group's commitment to preserving the natural darkness essential for the health of ecosystems and human circadian rhythms, as well as its role in reducing bird fatalities during migration.

In honor of these contributions, the resolution designates April 25, 2025, as Dark Sky Day in Texas and commends DarkSky Texas for its dedication to protecting the state's night skies. The organization also promotes dark sky tourism, exemplified by events like the star parties at the McDonald Observatory, and celebrates the communities that embrace their clear nighttime views. The Texas Senate expresses its high regard for DarkSky Texas by preparing an official copy of the resolution for the organization.
