Piercing the Sky

Satellite Trails Over Hobart Skies
Satellite trails are an increasingly visible sign of human impact on the night sky. As large constellations of satellites expand, long streaks of reflected sunlight appear in astronomical images, interfering with observations and altering the natural darkness of space.

This is closely tied to light pollution: while traditional light pollution comes from ground-based sources, satellites introduce a new, moving form of sky brightness. AltText: A striking vertical, long-exposure night photograph capturing an alpine landscape under a sky heavily crisscrossed by satellite trails. In the lower third, a rocky, dirt path winds through low-lying green and golden alpine shrubs toward a prominent outcrop of massive, weathered dolerite boulders. Above this ancient terrain, the dark night sky transitions from a deep teal-blue at the zenith to a hazy, light grey glow along the horizon. The sky is filled with a dense, chaotic grid of straight, intersecting white and faintly colored light trails left by passing satellites. Some trails appear as perfectly spaced dashed lines, slicing across the natural background of faint, static stars and contrasting sharply with the curved, subtle star trails visible on the left edge.
