It is not easy to observe Jupiter’s moons as more than points of light with Juno, because Juno will never get very close to any of the moons, but as its orbit shifts there will be opportunities to collect data on some of the moons.

For a second time, NASA has placed a spacecraft into orbit at Jupiter. The spacecraft operated exactly according to plan, and Juno successfully entered orbit today, July 5, 2016, UTC

We're now just about 12 hours away from Juno's Jupiter orbit insertion. As anticipation ramps up, NASA has released this sneak peek at JunoCam's approach movie, made of views of Jupiter and its largest moons shot during the final approach, up until about five days ago.

What is the solar system moon with the densest atmosphere? Most space fans know that the answer is Titan. A few of you might know that Triton's is the next densest. But what's the third? Fourth? Do any other moons even have atmospheres? In fact, they do; and one such atmosphere has just been discovered.

Europe's JUICE spacecraft will provide us with a detailed regional study of this icy moon of Jupiter.

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!

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.

Not many subjects remain for which it is possible to assemble everything that we know about it in one book. Even for those subjects for which our knowledge is limited, knowledge seems always to be expanding exponentially. This is not true, however, for the Galilean satellites of Jupiter.

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!

I was astounded to learn this morning that SOHO can not only see Jupiter, it can actually resolve Jupiter's moons (at least its two outer ones) as points of light separate from their planet!

As I wait for the MESSENGER Mercury Orbit Insertion webcast to start, I thought I'd fiddle with some images to point out that Mercury is a bridge between the scales of planets and the scales of moons.

Time to open the twenty-second door in the advent calendar. Where in the solar system are these degraded craters?

Here's a lovely amateur-produced color image of Jupiter's moon Callisto, or, as its artist Daniel Macháček calls it, "Titan without weather."

It's the second time I've posted with this provocative title. This time, it's in response to a new paper published last week in Science.

The first talk I attended at the Lunar and Planetary Science Conference in Houston was my one icy satellite talk for the day.

It was 400 years ago today that Galileo discovered smaller planets attending the planet Jupiter.
