Last week I posted a stack of Voyager Mission Status Bulletins, which were once the main resource for space enthusiasts to follow the dramatic events and photos of an in-flight space mission.

Photos like this always make me think about how unimportant size is in determining whether one of the worlds of the solar system is an exciting place.

We take for granted now the ability to get detailed mission updates in a timely fashion via the Web. But How did people get their mission status before the Web?

Amateur image mage Björn Jónsson has recently turned his attention back to Voyager 1's close-up images of Jupiter.

Following up on the story I first posted on August 22, the Jupiter impact fireball first noticed by Japanese amateur astronomer Masayuki Tachikawa has been independently confirmed by two other Japanese astronomers.

This may be a very common event after all: another optical flash has been observed on Jupiter, again from an observer far east of the Greenwich meridian, though it was not Anthony Wesley (for once).

Thanks to its active volcanic activity and sulfur-rich surface, Io is one of the most colorful worlds yet seen in the Solar System, save the Earth of course

Three years after New Horizons flew past Jupiter on its way to Pluto, the spacecraft has imaged the giant planet again.

Three months ago, grandiosely, I announced that I was going to survey volcanism across the solar system, and I began the journey on Earth. Then I failed to follow up.

When I wrote a post about Jupiter's missing South Equatorial Belt in May, I had three main questions: how long did it take for the belt to go away, has this happened before, and how can a planet as big as Jupiter change its appearance so quickly?

Time to take stock of what happened a day ago. The worldwide, round-the-clock nature of planetary science is both exhilarating and challenging!

The impact flash on Jupiter observed earlier today by Anthony Wesley has been confirmed by Philippines-based amateur astronomer Christopher Go.

On the same day as a team of astronomers released new Hubble Space Telescope images of last year's Jupiter impact, the original discoverer of the 2009 impact scar, Anthony Wesley, reported on an amateur astronomy forum that he had observed a new impact on Jupiter.

Via Daniel Fischer's Tweet about a blog entry by Astro BobI learned of something which should be obvious to anyone who has trained even a rather small telescope on Jupiter over the past few weeks: one of its iconic stripes is just plain gone.

Tomorrow is the 20th anniversary of the launch of the Hubble Space Telescope. It's hard to believe it's been going strong for so many years.

Yesterday I asked for suggestions for topics to write about, and you readers seem to have volcanoes on your minds!

As if Titan's methane rain weren't weird enough, Jupiter's now thought to have helium-neon rain.

Here's a lovely amateur-produced color image of Jupiter's moon Callisto, or, as its artist Daniel Macháček calls it,
