This week in 2011, the Juno mission to Jupiter launched from NASA’s Kennedy Space Center aboard an Atlas V-551 rocket.

The shadows cast by the roughness of the Moon’s surface create small cold spots for water ice to accumulate even during the harsh lunar daytime.

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.

NASA has selected SpaceX to provide launch services for Earth’s first mission to conduct detailed investigations of Jupiter's moon Europa.

This page showcases our resources for those interested in learning more about Jupiter.

The next full Moon goes by many names including the Buck Moon.

The probe flew closer to Jupiter's largest moon, Ganymede, than any other spacecraft in more than two decades.

A puzzler about the gas giant’s intense northern and southern lights has been deciphered.

Scientists are studying the effects of small impacts on Europa’s surface as they prepare to explore the distant moon with the Europa Clipper.

The spacecraft flew closer to Jupiter’s largest moon than any other in more than two decades, offering dramatic glimpses of the icy orb.

The first of the gas-giant orbiter’s back-to-back flybys will provide a close encounter with the massive moon after over 20 years.

Jupiter’s moon Europa has an icy crust covering a global ocean. The rocky layer beneath may be hot enough to melt, leading to undersea volcanoes.

On April 15, 2021, NASA’s Juno spacecraft captured the intriguing evolution of “Clyde’s Spot.”

A technique for scanning Mars rocks for microscopic fossils is also being developed to hunt for microbes on Enceladus, Titan, and Europa.

The spacecraft will use multiple flybys of the moon to investigate the habitability of this ocean world.

Set to launch next year, the agency’s Psyche spacecraft will explore a metal-rich asteroid in the main asteroid belt between Mars and Jupiter.

This image from NASA’s Juno mission captures the northern hemisphere of Jupiter around the region known as Jet N7.

A proposed mission called Io Volcano Observer (IVO) would visit Jupiter’s moon Io, which is a true volcanic wonderland.

The gas-giant orbiter is illuminating the provenance of Jovian polar light shows.

Zodiacal light is sunlight reflected toward Earth by dust orbiting the Sun. Juno scientists now think Mars may be the source of the dust.

Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA.

A wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way.

As astronomers discovered asteroids hiding in Jupiter’s Lagrange points, they began referring to them as “Trojan asteroids.”

JPL's lucky peanuts are an unofficial tradition at big mission events.

This view of Jupiter’s turbulent atmosphere from NASA’s Juno spacecraft includes several of the planet’s southern jet streams.
