Yet another Jupiter impact!? August 20, seen from Japan

Emily Lakdawalla • August 22, 2010

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).

Jupiter's faded belt: It's happened before, and it'll happen again

Emily Lakdawalla • June 16, 2010

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?

The June 3 Jupiter Impact: 22 hours later

Emily Lakdawalla • June 04, 2010

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

Confirmation of the Jupiter impact from Christopher Go

Emily Lakdawalla • June 03, 2010

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

A NEW! Impact on Jupiter

Emily Lakdawalla • June 03, 2010

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.

Jupiter has lost a belt!

Emily Lakdawalla • May 10, 2010

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.

Hubble turns 20

Emily Lakdawalla • April 23, 2010

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.

Where neon falls like rain

Planetary Society Advent Calendar for December 7: Jupiter

Emily Lakdawalla • December 07, 2009

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.

Four hundred and fourteen years since Galileo

Emily Lakdawalla • December 07, 2009

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.

Two new names in the solar system: Herse and Weywot

Emily Lakdawalla • November 12, 2009

Planetary Radio Q and A: Not-so-gassy giants

Emily Lakdawalla • November 04, 2009

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?"

Frame a Pluto portrait

Emily Lakdawalla • April 07, 2008

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.

New Horizons' Jupiter flyby was successful!

Emily Lakdawalla • February 28, 2007

According to a press release issued minutes ago, New Horizons has successfully completed its close flyby of Jupiter.

New Horizons update and a website roundup
