Will Juno’s Instruments Observe the Moons of Jupiter?

Candice Hansen • August 30, 2016

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.

Juno has arrived!

Emily Lakdawalla • July 05, 2016

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

A peek at the JunoCam approach movie

Emily Lakdawalla • July 04, 2016

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.

A moon with atmosphere

Emily Lakdawalla • April 08, 2015

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.

JUICE at Europa

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

Scale comparisons of the solar system's major moons

Emily Lakdawalla • July 10, 2013

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

One Ocean World Among Many

Jim Bell • June 03, 2013

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!

Instruments for the JUICE Jovian Mission

Van Kane • March 07, 2013

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.

Book Review: Atlas of the Galilean Satellites, by Paul Schenk

Emily Lakdawalla • November 18, 2011

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.

Scale solar system presentation slide, a provisional version for you to review

Emily Lakdawalla • September 15, 2011

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.

Update: Phobos and Jupiter and its moons!

Emily Lakdawalla • June 20, 2011

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!

Spotting Jupiter's Moons...with a Solar Telescope!?

Emily Lakdawalla • April 06, 2011

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!

Mercury: a moon-scale body

Emily Lakdawalla • March 17, 2011

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.

Door 22 in the 2010 advent calendar

Emily Lakdawalla • December 22, 2010

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

A new view of Callisto

Emily Lakdawalla • March 22, 2010

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

Titan: Callisto with weather

Emily Lakdawalla • March 16, 2010

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.

LPSC: Why Ganymede and Callisto are so different

Emily Lakdawalla • March 01, 2010

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

400 Years of the Galilean Satellites

Emily Lakdawalla • January 07, 2010

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