Rover fans have been excitedly watching the hills on Opportunity's horizon grow taller and taller as Opportunity rolls toward its destination, Endeavour crater.

Following up on the story I first posted on August 22, the Jupiter impact fireball first noticed by Japanese amateur astronomer Masayuki Tachikawa has been independently confirmed by two other Japanese astronomers.

This may be a very common event after all: another optical flash has been observed on Jupiter, again from an observer far east of the Greenwich meridian, though it was not Anthony Wesley (for once).

Thanks to its active volcanic activity and sulfur-rich surface, Io is one of the most colorful worlds yet seen in the Solar System, save the Earth of course

In response to Emily's entry about finally getting her hands on a subscription to the planetary science journal Icarus, I thought I would report on an article from the most recent issue: Geology of the Selk crater region on Titan from Cassini VIMS observations, by Jason Soderblom and 11 other scientists.

Over the last couple of days Cassini flew past Enceladus, Tethys and Dione, so there are lots of treats to see on the raw images website! You should go check it out for yourself, but here are a couple of real favorites.

You know, I could fill this blog almost entirely with the amazing images that Gordan Ugarkovic locates, processes into prettiness, and uploads to his Flickr account.

I've posted animations from Cassini before in which there are multiple moons moving around, but this is one of the coolest such sequences I've seen yet.

I've spent a pleasurable hour or so browsing over the latest release of images from Cassini to the Planetary Data System.

Here are two newly processed portraits of Saturn, showing the planet just after its equinox.

The Saturn system is always in motion, always changing. Saturn itself is a gas giant, with swirling storms, and like the other gas giants it has a host of moons flying around, perturbing each other's motions. And then there's the rings.

Since it doesn't look like the Rosetta mission is going to be releasing any color versions of their Lutetia close-encounter images any time soon, I figured it was time to make one.

Three months ago, grandiosely, I announced that I was going to survey volcanism across the solar system, and I began the journey on Earth. Then I failed to follow up.

Four times a year, the Cassini mission releases three months' worth of data gathered from Saturn and its moons to NASA's Planetary Data System.

As promised last week, Cassini has delivered its best photos yet of the tiny moon Daphnis, the ringmoon that is responsible for carving out the skinny Keeler gap at the outer edge of Saturn's A ring.

Here is a photo crafted from data that are nearly as old as I am, showing a beautiful sunrise on Mars.

Time to take stock of what happened a day ago. The worldwide, round-the-clock nature of planetary science is both exhilarating and challenging!

The impact flash on Jupiter observed earlier today by Anthony Wesley has been confirmed by Philippines-based amateur astronomer Christopher Go.
