It's a great time to go outdoors and look at planets. I have three glorious planetary portraits to share today, sent to me by amateur astronomer Jean-Luc Dauvergne.

Juno is now fewer than six months and 100 million kilometers away from Jupiter, and the Juno team is busily preparing for the arrival. Amateur astronomers are supporting them by taking lots of Jupiter photos.

On the 20th anniversary of Galileo's orbit insertion around Jupiter, amateur image processor Björn Jónsson shares some of the mission's first images of Jupiter's iconic massive storm.

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.

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.

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.

Europe's JUICE spacecraft will provide us with a detailed regional study of this icy moon of Jupiter.

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.

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?

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.

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.

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.

Cassini's unique views of Jupiter and Saturn.

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.

Van Kane

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.
