Terra Cognita

Pushing back the frontier, and filling in the blank spaces on the map.

Lesser-known views of Uranus and Neptune

Despite the fact that Voyager 2 returned relatively few high-resolution images from either Uranus or Neptune, there are many more photos in the archives than regularly make it to public view.

Planetary Society Weekly Hangout: The Ice Giants, with Heidi Hammel

My guest this was Planetary Society Board vice president Heidi Hammel. We discussed two planets near and dear to our hearts, Neptune and Uranus. What's new on these icy worlds since Voyager 2 passed by, and what are the prospects for their future exploration?

Mysterious Umbriel

Presenting a newly-processed version of Voyager 2's best images of Uranus' moon Umbriel.

Pretty picture: Neptune and Triton

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?

Voyager 1 revisited: Io and Europa transiting Jupiter

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

A couple of gems from the archives

We're still working on migrating content from the old to the new website. This week, that means I am looking, one by one, through some great amateur-processed space images.

A Voyager 1 anniversary mosaic

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.

What's up in the Solar System in August 2012

Welcome to the monthly roundup of our solar system's envoy of electronic explorers! All eyes are on Curiosity as it approaches Mars this weekend. Who will lend support at the Red Planet?

Cartoon: Voyager's ongoing adventures

I'm not sure what to make of this YouTube cartoon about Voyager, except to say that it's simultaneously heart-wrenching, funny, and adorable.

Pretty Picture: A snapshot of Voyager 1's departure from Jupiter

In this week's Snapshots from Space video, I talk about the Voyager 1 images of Jupiter -- how many there are (tens of thousands), and what a challenge they represent for image processors. But, I promise, the effort is worth it. Here's just one example: it's a color, crescent view of Jupiter, taken by Voyager 1 as it departed.

Iapetus' peerless equatorial ridge

A new paper in the Journal of Geophysical Research - Planets by Dombard, Cheng, McKinnon, and KayI claims to explain how Iapetus' equatorial ridge formed. Cool!

Bj�rn J�nsson's Voyager 1 Jupiter animation, new and improved

Late last year I posted an amazing video of Jupiter's moving clouds, an animation made from images that Voyager 1 took as it approached. Below is a new and improved version of that animation. The first one was based on 16 Voyager color photos; this one covers a much longer period of time, and includes 58 images.
