A case of the measles for Jupiter?

Emily Lakdawalla • November 26, 2013

Amateur astronomer Christopher Go has found Jupiter to be putting on a fun show for observers: it's sprouting little red spots "like it has a measles attack!"

Cosmos with Cosmos Episode 6: Travellers' Tales

Casey Dreier • November 25, 2013

The Voyager mission may be the ultimate expression of our desire to explore, but why does that will exist in the first place? Why is it unique to humans?

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.

Jupiter and Io from Pioneer 10

Ted Stryk • August 02, 2013

This is a parting shot of Jupiter and Io, taken December 5, 1973, by the Pioneer 10 spacecraft, the first to see either world as a crescent.

Movie SciFi With Real Science? What a Concept!

Mat Kaplan • July 30, 2013

This week's Planetary Radio features the new indy film that relies on the best available science to create a thrilling and inspiring human mission to Jupiter's moon.

In a New Light

Bill Dunford • April 15, 2013

Cassini's unique views of Jupiter and Saturn.

Checking in on Jupiter

Emily Lakdawalla • March 12, 2013

We don't have any spacecraft at Jupiter right now, which is a pity. Until we do, we have to rely upon Earth-based astronomers to monitor the changing face of the largest planet.

Instruments for the JUICE Jovian Mission

Van Kane • March 07, 2013

The European Space Agency (ESA) announced the list of instruments selected for its JUICE mission to explore the Jovian system for three years starting in the 2030 following a 2022 launch.

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.

Pretty picture: Jupiter photo from an unusual source

Emily Lakdawalla • December 26, 2012

A recently launched Earth-observing satellite is using the stars to practice its pointing, and caught a neat animation of Jupiter.

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.

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.

Snapshots From Space Video: Revealing Jupiter's (Mostly) Unseen Treasures

Mat Kaplan • March 18, 2012

Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.

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

Emily Lakdawalla • March 13, 2012

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.

Pretty pictures: Voyager 2 at Jupiter

Emily Lakdawalla • March 02, 2012

Here are two perfect examples of Voyager 2's amazing untapped treasures.

Checking up on Jupiter and Saturn

Emily Lakdawalla • February 10, 2012

It's amateur astronomers, not professionals, who are shouldering the burden of constant monitoring of the weather on Jupiter and Saturn. What's going on these days in the outer solar system?

At last: Rosetta's Mars flyby photos have been released!

Emily Lakdawalla • January 24, 2012

On February 24, 2007, the Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released two photos from the main science camera, OSIRIS.

Scale solar system presentation slide, a provisional version for you to review

Emily Lakdawalla • September 15, 2011

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

Blast from the past: Pioneer 10 and 11 pictures of Jupiter

Emily Lakdawalla • September 07, 2011

Here's a few pretty pictures that were recently dusted off by Ted Stryk. Pioneer 10 and 11 passed by Jupiter on December 4, 1973, and December 3, 1974, respectively. Here are three pictures from those two encounters, in versions newly processed by Ted from scanned photographic prints found during a research trip to NASA's Ames Research Center.

Jupiter's southern belt is coming back

Emily Lakdawalla • August 01, 2011

In a story that I've been following for quite a while, Jupiter's southern equatorial belt, having faded to white in 2009, is now well on its way back to its former red glory.
