Cosmos with Cosmos Episode 11: The Persistence of Memory

Uranus Awaits

Geraint Jones • October 18, 2013

It’s been a long time since anyone paid Uranus a visit. The Uranus system is, however, fascinating, as evidenced by the wealth of topics covered by the diverse group of planetary scientists who gathered to discuss it last week at the Paris Observatory.

Gravity assist

David Shortt • September 27, 2013

With the recent announcement by NASA that the 36 year-old spacecraft Voyager 1 has officially entered interstellar space at a distance from the sun about four times further than Neptune's orbit, and with Voyager 2 not far behind, it seems worthwhile to explore how humans managed to fling objects so far into space.

Voyager: A Tribute

Stephen J. Pyne • September 25, 2013

The Voyagers were special when they launched. They have become more so thanks to their longevity, the breadth of their discoveries, the cultural payload they carried, and the sheer audacity of their quest.

Lesser-known views of Uranus and Neptune

Emily Lakdawalla • May 28, 2013

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

Emily Lakdawalla • April 11, 2013

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?

Voyager 1 revisited: Io and Europa transiting Jupiter

Björn Jónsson • January 22, 2013

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

Emily Lakdawalla • September 10, 2012

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.

The Planetary Society Celebrates 35 Years of Voyager

Casey Dreier • September 07, 2012

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.
