The annual New Horizons Science Team Meeting was held last week at NASA's Ames Research Center.

Today the 365 Days of Astronomy podcast aired my contribution, Unmanned Space Exploration in 2011, about what to look forward to in solar system exploration this year.

I was browsing JPL's Planetary Photojournal today and noticed that they've posted an updated artist's concept of the Juno spacecraft, which is set to launch in August for a 2016 arrival at Jupiter.

Jupiter, always a pretty sight in the sky, is now worth visiting every day; the

Jupiter's faded belt may be coming back.

Ready to see something beautiful? Here's a team effort by Björn Jónsson and Ian Regan to create a really mesmerizing view of the motions of Jupiter's clouds.

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?

This is a new, big mosaic of Voyager 1 images, this time showing the Great Red Spot at high resolution.

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).

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

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.
