Joya-La Barreta Ecological Park in Querétaro, Mexico, has become Latin America’s first certified urban night sky reserve, recognized by DarkSky International in early 2023. Situated 8,520 feet above sea level, the park offers exceptionally clear views of stars and constellations, a rarity in urban areas increasingly impacted by light pollution. This certification by DarkSky promotes awareness about artificial lighting’s harmful effects. A 2023 study revealed that light pollution boosts global sky brightness by 10% annually, a trend in Mexico linked to urban expansion and increased lighting for security. Experts warn that artificial light disrupts natural cycles, affecting both humans and nocturnal species dependent on darkness.

To protect the night sky, local astronomers like Juan Carlos Hernández have led conservation initiatives, including community outreach, policy advocacy, and monitoring light pollution. Hernández, president of Querétaro’s Astronomical Society, stressed the park’s ecological sensitivity and highlighted Mexico’s 2021 General Law of Ecological Balance as essential for conservation. In 2023, he submitted a proposal to Querétaro’s Congress for better local regulation. Regular pollution reports to DarkSky assess sky conditions, while public events encourage community appreciation for the night sky. These efforts collectively aim to preserve this dwindling natural resource, enabling future generations to enjoy a pristine, star-filled sky.
