We’re spoiled, don’t you know? It was 10 years ago today that the Cassini spacecraft entered Saturn’s system, and it has been busily beaming back pictures of the ringed planet and its (many) moons ever since. We’ve learned more about seasons on Titan, investigated plumes on Enceladus, and examined phenomena such as auroras on Saturn.
Embedded in this story are 20 of our favourite pictures from Universe Today’s archive of Cassini discoveries, which you can check out below the jump.
It’s only a fraction of the more than 332,000 images received from the spacecraft, which is in excellent health and has seen its mission extended three times past its original 2008 expiry date. Additionally, more than 3,000 scientific papers have been generated. More cool stats in this NASA infographic.
And by the way, we’re not the only ones assembling memorable images to mark the anniversary. Check out NASA’s favourite Cassini pictures of the past decade, or our friend Phil Plait’s Bad Astronomy list. Also, here is NASA’s opinion of the top 10 discoveries at the ringed planet.
While thinking about Cassini, also don’t forget Huygens, the lander that descended to the surface of Titan in 2005. More on that in this past Universe Today anniversary story.
The full mosaic from the Cassini imaging team of Saturn on July 19, 2013… the “Day the Earth Smiled”
In this unique mosaic image combining high-resolution data from the imaging science subsystem and composite infrared spectrometer aboard NASA’s Cassini spacecraft, pockets of heat appear along one of the mysterious fractures in the south polar region of Saturn’s moon Enceladus.

This image taken by the Cassini orbiter on Oct. 15, 2007, shows Saturn’s A and F rings, the small moon Epimetheus and smog-enshrouded Titan, the planet’s largest moon. The image is colorized to approximate the scene as it might appear to human eyes. (Credit: NASA/JPL/Space Science Institute)

This false-color composite image shows Saturn’s rings and southern hemisphere. The composite image was made from 65 individual observations by Cassini’s visual and infrared mapping spectrometer in the near-infrared portion of the light spectrum on Nov. 1, 2008.

This mosaic of images from NASA’s Cassini spacecraft shows three fan-like structures in Saturn’s tenuous F ring. Such “fans” suggest the existence of additional objects in the F ring. Image credit: NASA/JPL/SSI
Cassini came within 25 kilometers (15.6 miles) of the surface of Enceladus on Oct. 5, 2008. Image credit: NASA/JPL/Space Science Institute
