Serendipitous Juno Spacecraft Detections Shatter Ideas About Origin of 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. Astronomers have long thought that the dust is brought into the inner solar system by a few of the asteroid and comet families that venture in from afar. But now, a team of Juno scientists argues that Mars may be the culprit.

Deep Jet Streams in Jupiter’s Atmosphere
This view of Jupiter’s turbulent atmosphere from NASA’s Juno spacecraft includes several of the planet’s southern jet streams. Using data from Juno’s instruments, scientists discovered that Jupiter’s powerful atmospheric jet streams extend far deeper than previously imagined. Evidence from Juno shows the jet streams and belts penetrate about 1,800 miles (3,000 kilometers) down into the planet.

NASA’s Juno Mission Expands Into the Future
NASA has authorized a mission extension for its Juno spacecraft exploring Jupiter. The agency’s most distant planetary orbiter will now continue its investigation of the solar system’s largest planet through September 2025, or until the spacecraft’s end of life. This expansion tasks Juno with becoming an explorer of the full Jovian system.

NASA's Juno Spacecraft Updates Quarter-Century Jupiter Mystery
Twenty-five years ago, NASA sent history's first probe into the atmosphere of the solar system's largest planet. But the information returned by the Galileo probe during its descent into Jupiter caused head-scratching: The atmosphere it was plunging into was much denser and hotter than scientists expected.
