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.

Jupiter has been high overhead at sunset for several months, a brilliant light that's easy to spot even when the sky is still bright at dusk; but it's now moving quickly to the west as Earth speeds ahead of Jupiter's more stately march around the Sun.

Galileo, the scientist, discovered the Galilean satellites of Jupiter four hundred years ago next month, while Galileo, the mission, arrived at Jupiter to study those moons in situ fourteen years ago Sunday.

Via the USGS I learned that Jupiter has passed a milestone of sorts, and now has fifty named satellites.

On Planetary Radio's "Questions and Answers" I answered this question: "I read that Uranus got its tilt when it was hit by another object. What does it mean for a ball of gas to be hit -- wouldn't another object just pass through it?"

As New Horizons continues its journey (it's now approaching the orbital distance of Saturn, though it's very far from that planet in space), the mission is taking advantage of the recent experience with the Jupiter flyby to plan out the science operations for the Pluto-Charon encounter.

A year after its launch on January 19, 2006, New Horizons is fast closing in on Jupiter, the first target on its near decade-long journey. On February 28 the spacecraft will approach to within 2.3 million kilometers (1.4 million miles) of Jupiter before speeding along on to its way to the edge of the solar system.

Alan Stern just posted a detailed update on the status of New Horizons in his PI's Perspective blog on the mission website.

Before I get to my notes from OPAG I want to minimally acknowledge today's news, which I'll have to get to in more detail later.

Home. Family. This will be Voyager's enduring legacy: It has changed forever the feelings raised by those words. Through its robotic eyes we have learned to see the solar system as our home. Through its portraits of the planets we know that they are part of our family. Apollo astronauts showed us a tiny Earth alone in the blackness of space. Now, with these images, Voyager has shown us that Earth is not really alone. Around our parent Sun orbit sibling worlds, companions as we travel through the Galaxy.
