When the sun sets and nature winds down for the night, another light—one not born of stars or fireflies—takes over the landscape. Streetlights, billboards, vehicle headlights, and glowing cityscapes brighten the night, not just for us, but for the countless creatures that depend on darkness for survival.

But what happens when night no longer feels like night?

Artificial light at night (ALAN) has become one of the most overlooked forms of pollution, subtly yet profoundly disrupting the rhythms of ecosystems around the world. While it may seem harmless to us, for many nocturnal species, this intrusion of brightness is a source of stress, disorientation, and in some cases, mortality.
