Here’s a beautiful photo taken by a crew member aboard the International Space Station showing the crescent moon above Earth’s atmosphere, a hazy band of bright blue separating our world of life from the inhospitable harshness of space. An amazing shot, but what’s even cooler about it is that it looks remarkably like an illustration…

Details of Dione
Here’s some awesome just-released raw images from Cassini’s flyby of Dione earlier this morning! The low angle of sunlight brings out the detail of the moon’s rugged terrain, peppered with ancient craters of all sizes and gouged by long scars of steep, icy cliffs. Fantastic! Thanks to team leader Carolyn Porco for alerting us to…
Breaking the Ice
Here’s a look at the frozen crater Cilix, a rare ice-filled dent in the scoured and resurfaced face of Europa. Taken by the Galileo spacecraft in 1998, this image has been reassembled from raw data and color-calibrated by Gordan Ugarkovic to highlight the surface detail of this fascinating frozen cueball of a moon. Covered by…
Blast from the Past
This photo of Neptune’s largest moon Triton was taken by Voyager 2 on August 24, 1989…nearly 21 years ago! With a resolution of about six miles per pixel it reveals the rugged mountainous terrain of this frozen moon in the far reaches of our solar system, including its signature “cantaloupe terrain” seen here in the…
A Cassini Composition
Cassini took this beautiful image of a crescent-lit Enceladus shadowed against Saturn’s silhouette during Friday’s flyby, demonstrating once again its uncanny ability to capture wonderfully-composed shots that illustrate the inherent beauty of our family of planets. Enceladus is the now-famous moon with “jet-power”…continually erupting geysers spray water ice out into space from long “tiger stripe”…
An Icy Crescent
A color-composite image of Saturn’s moon Enceladus, assembled from RGB raw image data recorded by Cassini on July 4, 2010. The moon’s heavily textured and highly-reflective icy terrain is nicely accentuated by the low angle of sunlight. The Cassini spacecraft was over 104,000 miles from Enceladus when the images were taken. Image: NASA/JPL/SSI. Edited by…
Daphnis Close-up
On July 5 the Cassini spacecraft took this image of Daphnis, a 4.5-mile-wide shepherd moon that orbits Saturn within the Keeler Gap. It’s the closest image yet of Daphnis, a moon that’s famous for the scallop-edged gravitational wake it makes on the edges of the gap as it passes. Read more on the Cassini mission…
A World of Secrets
Wrapped in its clouds and haze Saturn’s moon Titan teases us with its secrets. What sort of strange geologic events are happening on its surface? Volcanoes oozing water ice, natural gas rainstorms, rivers flowing with liquid methane into enormous glassy lakes, temperatures that would freeze most Earthly creatures solid within minutes. And now, the big…
Wispy Lines
A closer look at the surface of Rhea, Saturn’s second-largest moon, reveals some of its signature “wispy lines”…the bright exposed faces of steep cliffs on the icy 950-mile-wide moon. Taken by the Cassini spacecraft on June 3, 2010, the image above has been level-adjusted to bring out surface details. Being composed of 75% water ice,…
Hyperion
Here’s a wonderful color mosaic of Saturn’s moon Hyperion, assembled by Gordan Ugarkovic from four Cassini narrow-angle camera images. The moon’s heavily cratered sponge-like surface can be seen in vivid detail due to the high phase angle of sunlight, making its rough texture even more pronounced. At 255 x 163 x 137 miles in diameter,…
Titanesque
Here’s an image of Titan as seen by Cassini on May 23, 2010. I combined data from the red, green and blue color filters as well as overlaying some surface detail of the moon’s dark dune fields captured with the spacecraft’s cloud-piercing near-infrared camera.

Sinking the Shot
Alan Shepard may have played some moon golf during his visit in 1971 but even he wouldn’t have been up to par with this course. 😉 This photo shows the trail of a house-sized (33-foot-wide) lunar boulder that has rolled downhill and come to rest inside the rim of a crater. The image was taken…
