There were many, many treats waiting on the Cassini raw images website this morning. Yesterday, Cassini traversed the G ring, taking photos all the way.

The January 1, 2010 Cassini imaging data release includes everything acquired by Cassini from January 1 to March 30, 2009 in all its high-quality glory.

This one is fresh from the spacecraft! The data were captured yesterday, December 26, by Cassini during its best yet imaging encounter with the small ringmoon Prometheus, and showed up on the Cassini raw images website today.

I love posting animations of Cassini images that I compose from frames grabbed from the mission's raw images website, but they are shoddy compared to the versions that eventually come out from the mission's imaging team.

My inbox was exploding this morning with messages about a tremendously cool animation released this morning by ESA's Mars Express team. It shows Phobos crossing Deimos, in what's known as a

Here's another weird-looking one, though it's less weird from this particular, polar point of view than it is when viewed from the side.

Epimetheus is one of the many small moons of Saturn that are referred to by the Cassini mission team as

Thanks to Mike Malaska for the tip on this one. The image is part of an animation that ends with Rhea transiting Saturn.

This image goodie was produced from the raw images from Cassini's close encounter with Saturn's geyser moon Enceladus yesterday by Gordan Ugarkovic.

Last week, planetary astronomers Anne Verbiscer, Michael Skrutskie, and Doug Hamilton published a paper in Nature succinctly titled

Saturn is rapidly approaching equinox, where the Sun passes through the ring plane (south-to-north, i.e. the northern vernal equinox), and its ring system (i.e. its great now-gloomy poorly-lit circles of large blocks of water ice) is starting to show some really interesting behavior.

Another thing I've been trying to catch up on is the daily imaging activities of Cassini, but that, too, has been tough because Cassini has been taking so dang many pictures!

Saturn is surrounded by a crowded family of rings and moons, and two of those moons -- Epimetheus and Janus -- orbit Saturn so close together that it seems as though their different orbital speeds should make them crash into each other.

I've just resurrected a feature on the site that has been lost since our redesign: the

Here is a gorgeous color mosaic of Hyperion assembled by amateur image processor Mattias Malmer from images from the recent flyby.

I've finally worked my way through all of the Hyperion images that were returned from the last flyby. It's a wonderful data set.

I got an email last night from Anne Verbiscer, whom I had contacted about rounding up some amateur astronomers to help the Cassini mission with some photometric observations of Hyperion.
