This week's Planetary Radio features the new indy film that relies on the best available science to create a thrilling and inspiring human mission to Jupiter's moon.

A few presentation slides with pretty pictures, sized to scale, of the large moons of the solar system.

I'm absolutely floored when I stop to think that our beautiful blue ocean is only one of perhaps a half dozen or more oceans on other worlds in our solar system, and only one of probably millions (or more) oceans on other Earth-like planets in our galaxy. Oceans abound!

A look at an older paper describing Galileo's possible sighting of individual ring particles orbiting Jupiter as companions to its inner moon Amalthea.

Cassini's unique views of Jupiter and Saturn.

On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.

Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.

We don't have any spacecraft at Jupiter right now, which is a pity. Until we do, we have to rely upon Earth-based astronomers to monitor the changing face of the largest planet.

The European Space Agency (ESA) announced the list of instruments selected for its JUICE mission to explore the Jovian system for three years starting in the 2030 following a 2022 launch.

Ever wonder what it would taste like if you could lick the icy surface of Jupiter’s Europa? The answer may be that it would taste a lot like that last mouthful of water that you accidentally drank when you were swimming at the beach on your last vacation.

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

A recently launched Earth-observing satellite is using the stars to practice its pointing, and caught a neat animation of Jupiter.

We're fighting for the restoration of NASA's planetary sciences budget to return to its 2012 level. What does that get us? New financial analysis from our sources in the scientific community provides us a glimpse.

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

Björn Jónsson

Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.

To celebrate ESA's selection of the JUICE mission to Jupiter, Ted Stryk produced a new global view of Europa from Galileo data.

Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.

Emily Lakdawalla

In this week's Snapshots from Space video, I talk about the Voyager 1 images of Jupiter -- how many there are (tens of thousands), and what a challenge they represent for image processors. But, I promise, the effort is worth it. Here's just one example: it's a color, crescent view of Jupiter, taken by Voyager 1 as it departed.

Here are two perfect examples of Voyager 2's amazing untapped treasures.

It's amateur astronomers, not professionals, who are shouldering the burden of constant monitoring of the weather on Jupiter and Saturn. What's going on these days in the outer solar system?
