Probing Titan's Atmosphere

Sarah Hörst • August 26, 2013

By now I hope that everyone has seen some of the spectacular images of the Saturn system (and especially Titan!) from the Cassini-Huygens mission. However, the measurements that often make my heart race are taken by instruments that reveal Titan in ways that our eyes cannot see.

Pretty picture: spectacular Saturn and Titan

Emily Lakdawalla • August 15, 2013

A lovely view of the ringed planet and its hazy moon seen from nearly behind them just a few days ago.

Terra Cognita

Pushing back the frontier, and filling in the blank spaces on the map.

Jani Radebaugh, Titan Explorer

Robotic space exploration is human exploration. Meet one of the people behind the machines.

Pretty picture: Looking backward

Emily Lakdawalla • July 23, 2013

Here it is: the view from Saturn of our Earthly home, one and a half billion kilometers away. We see Earth and the Moon through a thin veil of faintly blue ice crystals, the outskirts of Saturn's E ring. Earth is just a bright dot -- a bit brighter than the other stars in the image, but no brighter than any planet (like Saturn!) in our own sky.

Return of the Pale Blue Dot

Meet some worlds that were nearly shattered, literally.

The Shores of the Kraken Sea: Great Place Names in the Solar System

Bill Dunford • May 28, 2013

Nothing reflects the romance of deep space exploration more than the evocative names of places on the planets and moons.

Mimas and Pandora dance

Emily Lakdawalla • May 15, 2013

I've been out of town for a couple of days and am overwhelmed with work and an overflowing email box. So what do I do about that? I ignore what I'm supposed to be doing and play with Cassini raw image data, of course. Here is a "mutual event" of Mimas (the bigger moon) and Pandora (the outer shepherd of the F ring).

One of my favorite image processing tricks: colorizing images

Emily Lakdawalla • April 23, 2013

An easy image processing trick -- using lower-resolution color data to colorize a black-and-white photo -- is relied upon by many space missions to keep data volumes low. Here's how to do it.

In a New Light

Bill Dunford • April 15, 2013

Cassini's unique views of Jupiter and Saturn.

First Analysis: the NASA Planetary Science Budget for 2014

Van Kane • April 10, 2013

No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.

One Day in the Solar System

Bill Dunford • April 08, 2013

Dispatches from five different worlds--all sent by robotic spacecraft on the same day.

LPSC 2013: License to Chill (or, the solar system's icy moons)

Emily Lakdawalla • March 27, 2013

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.

The Stormscapes of Saturn

Bill Dunford • March 04, 2013

Look past the rings, and Saturn is even stranger--and more breathtaking.

Arc of Ice and Light

Bill Dunford • February 18, 2013

When the sunlight catches it just right, Saturn's F Ring is something to see.

Enceladus: A problem of contrast

Emily Lakdawalla • January 30, 2013

Time for my quarterly foray into the Cassini archival science data! The very first image I downloaded from the January 1, 2013 data release presented an interesting challenge to my image processing skill. I'll show you the pretty picture of Enceladus and then explain how I processed it.

That amazing image of Saturn's north pole just got better: now, it moves!

Emily Lakdawalla • November 28, 2012

Remember the amazing photo of Saturn's north pole that I posted yesterday? Now, thanks to an amateur image processor, it moves, and the motions of the individual clouds within the belts are mesmerizing.

Staring into Saturn's baleful eye

Emily Lakdawalla • November 27, 2012

Amazing photos have just come back from Cassini, of swirling clouds surrounding Saturn's north pole.
