The Zodiacal Light
Look up to the night sky just before dawn or after dusk and you might see a faint column of light extending up from the horizon. That luminous glow is the zodiacal light, or sunlight reflected toward Earth by a cloud of tiny dust particles orbiting the Sun.
The “false dawn” has long puzzled astronomers, but findings from NASA’s Juno space probe released in March 2021 suggest that dust from our neighboring planet, Mars, may be to blame. Learn more about this new discovery in Science of the Zodiac.
