Jupiter Weather Report: 2014/15 Apparition
A summary of Jupiter's changing face as seen from Earth during its 2014/2015 apparition.
New Concepts to Explore the Jovian System
Last year, NASA’s managers invited the European Space Agency to propose a small spacecraft to explore the Jovian system. Van Kane describes the recently-posted results of ESA's concept studies for two possible missions.
Towards a Jupiter Weather Forecast
Trying to keep track of the ever-changing face of Jupiter is a pretty big challenge—its a dynamic world that can fascinate and surprise every time we turn our telescopes towards it.
New Robotic Spacecraft Posters
Another round of posters to celebrate historic planetary missions.
Jupiter's changing face, 2009-2015
Damian Peach's photo-documentation of Jupiter helps us monitor the giant planet's ever-changing patterns of belts, zones, storms, and barges, during a time when no orbiting missions are there to take pictures.
Looking Down On Jupiter's North Pole
Ted Stryk shares the most direct view of a Jovian pole ever captured by a spacecraft.
JUICE at Europa
Europe's JUICE spacecraft will provide us with a detailed regional study of this icy moon of Jupiter.
Voyager 3 Project
In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.
A Tale of Two Posters: Sediment on Mars and Searching Jupiter's Rings
A close look at two international planetary science poster presentations from the 2013 AGU Fall Meeting featuring sediment experiments to better understand Martian geomorphology and Juno's plans for exploring Jupiter's ring system.
A case of the measles for Jupiter?
Amateur astronomer Christopher Go has found Jupiter to be putting on a fun show for observers: it's sprouting little red spots
Cosmos with Cosmos Episode 6: Travellers' Tales
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
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
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!
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
Cassini's unique views of Jupiter and Saturn.
Checking in on Jupiter
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
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
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
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
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.
