During the spring equinox in the Northern hemisphere of the Earth after sunset, you can see the so-called "false dawn". This rare phenomenon creates a zodiac light — a glow above the horizon that is impossible to see in winter or summer, AccuWeather reports.
The phenomenon is observed in the western part of the sky. Experts from NASA's Jet Propulsion Laboratory explained that the zodiacal glow is the light of the Sun reflected from particles that orbit a star in the inner Solar System. These dust particles travel across the sky in the same plane as the moon.
The best time to observe is when the weather is cloudless, when the evening twilight gradually turns into darkness. The phenomenon resembles a hazy pyramid of light. Anyone who wants to see the glow should stay away from the sources of light pollution, which are large settlements.
People who live in the Southern Hemisphere may experience "false dawns" before sunrise.
The same phenomenon is observed during the autumnal equinox, but occurs before dawn in the Northern Hemisphere and after sunset in the Southern Hemisphere.
