Portraits of a planet.

NASA re-creates the Apollo 8 Earthrise using Lunar Reconnaissance Orbiter data

Andrew Chaikin • December 20, 2013 • 1

If there's one thing I've learned after decades of studying the first human voyages to another world, it's that there is always more to discover about Apollo. Case in point: The Apollo 8 Earthrise photo that became one of the iconic images of the 20th century.

Pretty picture: newly processed high-res view of a fractured icy moon, Dione

Emily Lakdawalla • December 04, 2013 • 4

Here's a lovely new view of Dione, one of the lovely mid-sized icy moons of Saturn, assembled by Daniel Macháček.

One for the history books: Stunning Saturn mosaic captured last week by Cassini

Emily Lakdawalla • October 16, 2013 • 5

I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.

Pretty picture: Neptune and Triton

Emily Lakdawalla • February 01, 2013 • 6

On a lonely evening, what is one to do but to dip into archival space image data and surface with a gorgeous photo of a crescent Neptune and Triton?

Chang'E 2 imaging of Toutatis succeeded beyond my expectations!

Emily Lakdawalla • December 14, 2012 • 19

The Chang'E 2 mission flyby of Toutatis succeeded in acquiring images. Oh my goodness, did they succeed. These, in combination with the incredible radar images still being acquired from Goldstone and innumerable optical observations, make Toutatis one of the best-studied asteroids in the solar system.

Blast from the past: Mariner 4's images of Mars

Emily Lakdawalla • December 10, 2012 • 5

While hunting for photos to use in a presentation, I came across a couple of different amateur takes on the Mariner 4 photo catalog.

Watching the slow shift of seasons on Titan

Emily Lakdawalla • November 06, 2012 • 1

A sharp-eyed amateur noticed two images of Titan taken 20 months apart from nearly exactly the same perspective, and they illustrate how the shifting of Saturn's seasons has brought change to Titan's atmosphere.

A huge color global view of Dione

Emily Lakdawalla • October 23, 2012

From the Cassini data archives comes a huge (5000 pixels square!) color image of Saturn's icy moon Dione, worth investigating from both near and far.

A Voyager 1 anniversary mosaic

Björn Jónsson • September 06, 2012

Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.
