Here are some recent postcards from Jupiter

Jason Davis • August 15, 2018

Let's check in on NASA's Juno spacecraft, which completed its 14th close flyby of Jupiter last month.

Eleven perijoves

Emily Lakdawalla • May 18, 2018

Seán Doran has made a cool visual index to the images that JunoCam took during Juno's first 12 closest approaches to Jupiter.

Juno meets Cassini: A new merged global map of Jupiter

Björn Jónsson • May 14, 2018

The Juno spacecraft that is currently orbiting Jupiter has obtained the first good images of Jupiter's polar regions. I am presenting here a combined global map of Jupiter, made from a Cassini map I made for the equatorial and temperate regions and polar maps made from the Juno JunoCam and JIRAM polar images.

Juno's 12th perijove in lifelike color

Emily Lakdawalla • May 11, 2018

With the help of some preprocessing of JunoCam images by Mattias Malmer, Don Davis shows us how Jupiter might have looked on April 1, 2018, if we'd been aboard Juno.

Space grade electronics: How NASA’s Juno survives near Jupiter

Jatan Mehta • April 17, 2018

Take a look at how electronics of spacecraft are built to survive the harshness of space environments.

Diving into Juno JIRAM data archives

Björn Jónsson • April 11, 2018

The Jovian Infrared Auroral Mapper (JIRAM) instrument can obtain images in two infrared bands. JIRAM can see the nightside of Jupiter (including the winter pole) and takes spectacular animations.

#AGU17: Spherical harmonics, gravity, and the depth of winds at Jupiter

Emily Lakdawalla • December 20, 2017

Results from the Juno gravity science experiment presented at last week's American Geophysical Union meeting suggest Jupiter's winds penetrate only to 3000 kilometers deep.

#AGU17: JunoCam science

Emily Lakdawalla • December 18, 2017

JunoCam may be an outreach instrument, but its superb photos of storms on Jupiter are providing plenty of data for scientists to talk about.

Brief note from #AGU17: Juno observes volcanism on Io

Emily Lakdawalla • December 13, 2017

At the American Geophysical Union meeting, members of the Juno team showed observations of active volcanism on Jupiter's moon Io.

New treasures from Juno: Jupiter dazzles during fourth close approach

Björn Jónsson • March 27, 2017

Image processor Björn Jónsson shares some of his latest stunning images of Jupiter, created using data from NASA's Juno spacecraft.

Juno just flew past Jupiter for the fifth time. What have we learned from the mission so far?

Anna Scott • March 27, 2017

There's no verdict quite yet on the giant planet's core, and scientists are still gathering clues about the accuracy of our current solar system formation models.

Planetary discovery over the past quarter century

Steven Hauck • December 20, 2016

2016 marks the 25th anniversary of the creation of what has become one of the primary venues for the publication of research in planetary science: the Journal of Geophysical Research: Planets. This occasion is a good opportunity to look back at what we have learned in this era of expanded exploration and to try to take a peek at the future.

What's up in the solar system, November 2016 edition: Cassini takes a leap, ExoMars starts science, Long March 5 launch

Emily Lakdawalla • November 01, 2016

Cassini is going to make a major change to its orbit, getting much close to Saturn, setting up 20 "F-ring" orbits. ExoMars will get two science orbits before beginning aerobraking. Long March 5 will have its first launch, while many Earth-observing missions, including Himawari-9 and GOES-R, will go up. But Juno science is on hold.

Juno to delay planned burn

Emily Lakdawalla • October 16, 2016

The Juno mission posted a status report late Friday afternoon, indicating that they will not perform the originally planned period reduction maneuver during their next perijove (closest approach to Jupiter) on October 19. The delay changes the start date of the science mission and also all the future dates of Juno's perijoves.
