Scale solar system presentation slide, a provisional version for you to review

Emily Lakdawalla • September 15, 2011

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

Blast from the past: Pioneer 10 and 11 pictures of Jupiter

Emily Lakdawalla • September 07, 2011

Here's a few pretty pictures that were recently dusted off by Ted Stryk. Pioneer 10 and 11 passed by Jupiter on December 4, 1973, and December 3, 1974, respectively. Here are three pictures from those two encounters, in versions newly processed by Ted from scanned photographic prints found during a research trip to NASA's Ames Research Center.

Jupiter's southern belt is coming back

Emily Lakdawalla • August 01, 2011

In a story that I've been following for quite a while, Jupiter's southern equatorial belt, having faded to white in 2009, is now well on its way back to its former red glory.

Update: Phobos and Jupiter and its moons!

Emily Lakdawalla • June 20, 2011

Remember that neat picture and movie of Phobos passing by Jupiter that I posted last week? Several people asked me where Jupiter's moons were, and I just assumed that they weren't visible. I was wrong; Mars Express spotted Jupiter's moons along with the planet and Mars' moon!

Bj�rn J�nsson's Voyager 1 Jupiter animation, new and improved

Emily Lakdawalla • May 16, 2011

Late last year I posted an amazing video of Jupiter's moving clouds, an animation made from images that Voyager 1 took as it approached. Below is a new and improved version of that animation. The first one was based on 16 Voyager color photos; this one covers a much longer period of time, and includes 58 images.

Memo to early risers: Look up!

Emily Lakdawalla • May 02, 2011

There is a traffic jam of planets on the eastern horizon in the early morning right now and for the next several weeks, a prize for those of you who have to rise before dawn.

The scale of our solar system

Emily Lakdawalla • May 02, 2011 has taken advantage of the infinitely scrollable nature of Web pages to produce a really cool infographic on the scales of orbital distances in the solar system.

Historical PDF: "The Voyager Flights to Jupiter and Saturn"

Emily Lakdawalla • April 20, 2011

A while ago I posted all 99 issues of the Voyager Mission Status Bulletins in PDF format, and now I have another cool item to add to that collection: NASA EP-191, "The Voyager Flights to Jupiter and Saturn."

Spotting Jupiter's Moons...with a Solar Telescope!?

Emily Lakdawalla • April 06, 2011

I was astounded to learn this morning that SOHO can not only see Jupiter, it can actually resolve Jupiter's moons (at least its two outer ones) as points of light separate from their planet!

Checking in on Jupiter: the belt is coming back

Emily Lakdawalla • March 25, 2011

Since it's been several months since I last took a look at Jupiter, I thought it was time to see what's up with the South Equatorial Belt.

LPSC 2011: Wanted: Pioneer 10 & 11 digital data

Emily Lakdawalla • March 11, 2011

This is both a Lunar and Planetary Science Conference (LPSC) update and a public service announcement. Ted Stryk has been working for years to locate the original Pioneer 10 and 11 image data from the Jupiter and Saturn encounters.

The Solar System from the Inside Out - and the Outside In

Emily Lakdawalla • February 18, 2011

Space probes grant us perspective, the ability to see our place within the vastness of the solar system. But opportunities to see all of the solar system's planets in one observation are rare. In fact, there's only been one opportunity on one mission to see the whole solar system at once, until now.

Snapshots from Space: Voyager views of the Great Red Spot, Björn Jönsson

Emily Lakdawalla • February 10, 2011

I've got a new column in the Planetary Society's member magazine, The Planetary Report, called "Snapshots from Space," highlighting really cool amateur-processed images. I'm excited to have the opportunity to help these people get their work published!

Io and Jupiter from Voyager 1

Emily Lakdawalla • January 31, 2011

Here's an image I've been meaning to post for months, a new mosaic from Voyager 1 by Ted Stryk of Io crossing Jupiter's terminator as it neared closest approach.

Report from the 2011 New Horizons Science Team Meeting

Ted Stryk • January 24, 2011

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

365 Days of Astronomy Podcast: Unmanned Space Exploration in 2011

Emily Lakdawalla • January 12, 2011

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.

Juno in an alternate universe

Emily Lakdawalla • January 04, 2011

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's outbreak is spreading

Emily Lakdawalla • November 22, 2010

Jupiter, always a pretty sight in the sky, is now worth visiting every day; the "outbreak" that heralds the return of Jupiter's formerly red, now fadedsouth equatorial belt is expanding and multiplying.

The Disturbance is Starting

Emily Lakdawalla • November 11, 2010

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.
