In Part 2 of this three-part astronomy series, Donna Burton, affectionately known as Donna the Astronomer, shines a light on the growing problem of light pollution. She explains how excessive, misdirected lighting not only dims our view of the stars but also disrupts natural ecosystems. Donna shares simple, practical changes—like using warm, shielded lights only when needed—that can reduce glare, save energy, and restore the wonder of our night sky. A powerful call to protect both our planet and the stars above.
