Nine years in space. 28 orbits of Jupiter. Textbooks rewritten. And I’m just getting started. This account is combining with @NASASolarSystem – join me there for continuing updates from my mission to Jupiter, along with other expeditions to the worlds of our solar system.

Nine years ago today, I began my journey to Jupiter. See these interviews with members of my team to hear more about what we have learned:

RT @Dr_ThomasZ: The swirling atmosphere we see on Jupiter is home to violent storms. @NASASolarSystem’s Juno mission discovered new evidenc….

The second image comes from my JunoCam instrument, with small bright "pop-up" clouds that rise above the surrounding features, thought to be the tops of violent thunderstorms. Credit: NASA/JPL-Caltech/SwRI/MSSS/Kevin M. Gill © CC BY.

The first image is an illustration, based on actual data my instruments obtained, that depicts high-altitude electrical storms on Jupiter. Full caption at Image Credit: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt.

Shallow lightning, clouds of ammonia and water, and a hail of “mushballs” – my instruments are revealing more about Jupiter’s stormy interior:

In the next few hours I’ll be making my 28th close pass by Jupiter (as simulated here by @NASASolarSystem’s Eyes on the Solar System: . Learn more about my mission at

Jupiter’s moon Ganymede is larger than the planet Mercury, the only moon in the solar system known to have its own magnetic field. I captured infrared images that provide the first glimpse of Ganymede's icy north pole. Learn more:

Amateur astronomer Clyde Foster spied a new feature in Jupiter’s clouds…I captured a detailed look at “Clyde’s Spot” when I zoomed by just two days later. #CitizenScience for the win. See more: JunoCam image processing by Kevin M. Gill

Racing stripes: Jupiter is huge, but makes a full rotation in just 10 hours. This creates powerful jet streams that divide its clouds into distinctive bands, as seen in this striking JunoCam image processed by citizen scientist David Marriott. Details:

I’ve teamed up with @NASAHubble and the ground-based @GeminiObs observatory to probe the powerful storms on Jupiter, including the "radio light show" produced by lightning flashes up to three times more energetic than Earth's largest bolts. See more:

A rose by any other name…🌹.This JunoCam image processed by Mary J. Murphy offers an especially colorful take on Jupiter’s Great Red Spot. Details:

Remembering on this #EarthDay the last time I flew by our home planet, and how unique and beautiful it looks from afar. #EarthDayAtHome

What I saw on my last close pass by Jupiter on April 10: the complex topography of the planet’s cloud tops. Details at: 📸 Image processed by Kevin M. Gill

Happening now: I’m passing low over the cloud tops of Jupiter, as simulated here by the @nasa_eyes visualization. Current speed relative to Jupiter: 128,000 mph (206,000 kilometers per hour) and rising. Get the latest mission news at
