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.

An internal ocean on Ganymede: Hooray for consistency with previous results!

Posted by Emily Lakdawalla on 2015/03/12 07:25 CDT | 8 comments

A newly published paper confirms a subsurface ocean at Ganymede. An ocean there was already suspected from its magnetic field and predicted by geophysics; new Hubble data confirms it, and even says it is in the same place we thought it was before. Such consistency is rare enough in planetary science to be worth celebration.

One Ocean World Among Many

Posted by Jim Bell on 2013/06/03 03:53 CDT | 6 comments

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!

Checking up on Jupiter and Saturn

Posted by Emily Lakdawalla on 2012/02/10 01:51 CST

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?

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

Posted by Emily Lakdawalla on 2011/11/18 12:59 CST

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.

Update: Phobos and Jupiter and its moons!

Posted by Emily Lakdawalla on 2011/06/20 03:53 CDT

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!?

Posted by Emily Lakdawalla on 2011/04/06 12:27 CDT

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

Posted by Emily Lakdawalla on 2011/03/17 06:15 CDT

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.
