Zodiacal Light Fades as Spring Transitions to Summer
Zodiacal Light Fades as Spring Transitions to Summer
US · Published May 17, 2026
The zodiacal light, a soft, cone-shaped glow caused by sunlight scattering off interplanetary dust, is becoming harder to observe as spring transitions into summer.
This phenomenon is visible after sunset, stretching above the western horizon through the constellations Taurus, Gemini, and Cancer.
The bright planets Venus and Jupiter can help guide observers to the ecliptic, where the zodiacal light is most prominent.

Why It's Important?

The fading visibility of the zodiacal light marks the end of its springtime viewing window. Stargazers and astrophotographers in the Northern Hemisphere, particularly those at 40° N latitude, are encouraged to take advantage of tonight's conditions before the phenomenon becomes obscured by the brighter summer skies. The waxing crescent Moon, with minimal illumination, provides an optimal opportunity for observation. However, light pollution and atmospheric conditions may still hinder visibility in urban areas.
