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.

Outside In

Bill Nye • September 07, 2011

Outside In, a film made from real space images that takes you on a soaring journey past our nearby worlds.

Pretty picture: Saturn from very close up

Emily Lakdawalla • August 24, 2011

I haven't checked in on Cassini lately. I went to the raw images page and found the frames for this very lovely, very close view of Saturn. It was taken by Cassini two days ago, as it was approaching periapsis.

Color versions of the recent Titan & moon beauty shots

Emily Lakdawalla • June 02, 2011

Last week I got very excited about a set of pictures that had appeared on Cassini's raw images website, but was sad that I couldn't make color versions myself. I was so excited that I failed to identify the little icy moon in the picture correctly.

Tantalizing photos of Titan, Dione, Tethys, and Saturn

Emily Lakdawalla • May 23, 2011

It figures. I just start a three-week trip, with my only computer a diminutive Netbook, and guess what's just been radioed across the 1.3 billion kilometers separating us and Saturn? A set of photos that should become -- when properly processed -- an iconic image from Cassini's fourteen-year mission to the Saturn system.

The scale of our solar system

Emily Lakdawalla • May 02, 2011

Space.com 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.

Watch Saturn's storms spin with VIMS

Emily Lakdawalla • April 28, 2011

A lot of attention has been paid recently to a storm in Saturn's northern hemisphere that is large and bright enough to be visible from Earth, but Saturn's atmosphere actually features lots more swirling storms. They can be hard to see, at least in visible wavelengths.

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."

Nearly behind Saturn

Emily Lakdawalla • April 19, 2011

Some recent photos that Cassini took from a position nearly in Saturn's shadow caught my eye, and I made a quick color composite. What an amazing view this would be if you were riding on the spacecraft!

365 Days of Astronomy Podcast: What's up in the second quarter of 2011

Emily Lakdawalla • April 07, 2011

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

Saturn's storm: A quick turnaround from Hubble

Emily Lakdawalla • March 28, 2011

Saturn's raging northern storm has been watched since it began by amateur astronomers, and now Cassini is getting in to the act too. Presumably once astronomers realized the magnitude of what was going on, some of Earth's great observatories were also occasionally pointed at the ringed planet to watch the storm grow.

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.

Pretty picture: Saturn storm

Emily Lakdawalla • March 08, 2011

To relieve this week's text-heavy LPSC posts, here's a brief one on an incredible panorama across Saturn's northern storm, taken on February 26 by Cassini and assembled by unmannedspaceflight.com member "Astro0."

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.

Some recent pictures of Saturn's northern storm

Emily Lakdawalla • February 07, 2011

There is a huge storm that's spreading across so much of Saturn that it's been readily visible even from Earth-based telescopes. Over the past couple of days a couple of new images of Saturn have appeared that show just how enormous the storm is today.

Goodies from the January 11 Rhea flyby

Emily Lakdawalla • January 12, 2011

Cassini got some incredibly tricky shots during its January 11 Rhea flyby!

Bye bye, Kodachrome, but "Kodak moments" will live on in space

Emily Lakdawalla • December 31, 2010

This week is the end for Kodachrome film. It's a casualty of the digital revolution.

The Year in Pictures: 2010

Emily Lakdawalla • December 30, 2010

I've just posted my annual roundup of significant images from planetary exploration in 2010.

An update to the Cassini Tour Page

Emily Lakdawalla • October 27, 2010

Where's the Cassini Saturn orbiter going to be in the next week -- or hundred weeks? It's all already planned out.

DPS 2010: Pluto and Charon opposition surges, Nix and Hydra masses, Pluto and Eris compositions

Emily Lakdawalla • October 25, 2010

An awful lot of the talks in the Pluto session on Tuesday morning, October 5, at the Division of Planetary Sciences meeting spent more time focusing on how bad weather conditions were during the astronomers' attempts to view Pluto as it occulted background stars than they did on any measurements or science that came out from the data.
