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.

Is Europa's ice thin or thick? At chaos terrain, it's both!

Emily Lakdawalla • November 17, 2011 • 6

Among Europa scientists there are two warring factions: the thick-icers and the thin-icers. The question is how thick is the ice shell that overlies Europa's subsurface ocean (the existence of which pretty much everyone agrees on).

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!

Europa on the Ropes

James Wray • June 11, 2011

For now, Mars continues to eclipse Jupiter's moon Europa (shown here to scale) in NASA's flagship mission plans, but not in its appeal to many planetary scientists.

Galileo's still producing discoveries: A magma ocean within Io!

Jason Perry • May 13, 2011

A fresh report was published online yesterday in Science Express on the discovery of a magma ocean beneath the surface of Io. Big news! This is a paper I've been looking forward to seeing for more than year and half.

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 • 1

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.

Ted Stryk • March 17, 2011

Here are Ted Stryk's notes from the sessions he attended in the afternoon of Thursday, March 10, at the 42nd Lunar and Planetary Science Conference.

LPSC 2011: Kirby Runyon on Mars, the Moon, Hartley 2, and Ganymede

Kirby Runyon • March 15, 2011

Kirby Runyon, a second-year grad student at Temple University, offered to send me some writeups of selected presentations from last week's Lunar and Planetary Science Conference, and I enthusiastically agreed.
