There were two new pictures posted on the New Horizons Science Operations Center website this morning, of Io, and if you enhance the images a bit, there are two clear volcanic plumes visible on the limb -- Tvashtar and Prometheus are active!
Iapetus is one of the many fascinating bodies in the Saturn system.
I wrote recently about a set of images of Saturn acquired by Cassini from a unique vantage point, well above the planet, looking down on the rings. Someone has taken up the challenge of assembling the 36 different images into a single mosaic, in color, and it is as lovely as I'd hoped.
Another recent, cool set of images that came down from Cassini was a series taken last week as the spacecraft crossed the ring plane.
I got an email from John Spencer this morning telling me that the mission had posted all of New Horizons' most recently acquired images on the mission website.
Over the weekend, Cassini acquired a set of images that will (I am assuming) eventually be used to produce a glorious portrait of the ringed planet from a point of view that's never been seen before.
Over time, Cassini's orbit apoapsis—the point on the orbit that is farthest from Saturn—has been shifting slowly toward Saturn's night side. Lately, this point of view has resulted in some truly lovely photos of the planet.
Today Nature published an article titled
Get used to this view of Home Plate and Husband Hill, because Spirit will be seeing a lot of it over the next 8 months, whenever power levels permit the rover to eke a little bit of science activity out of the day.
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
It's been a while since I posted some Cassini pictures here just because they were pretty.
The images from Cassini's Dione encounter yesterday have started coming back, and there is a really cool set of 16 pictures of Dione and Rhea.
Here is a gorgeous color mosaic of Hyperion assembled by amateur image processor Mattias Malmer from images from the recent flyby.
