Pretty Pictures: Amazing Asteroid Lutetia
Posted by Emily Lakdawalla on 2012/04/10 02:00 CDT
A long-awaited data set is finally public (well, long-awaited by me, at least). The Rosetta team has now published their data from the July 10, 2010 flyby of asteroid (21) Lutetia. This data set is absolutely stunning, and my friends in the amateur image processing community wasted no time in creating art out of it.
Pretty picture: Janus and Saturn
Posted by Emily Lakdawalla on 2012/04/04 12:15 CDT
In the last few days as it's rounded periapsis in its current orbit of Saturn, Cassini has taken a lot of great photos of Saturn's moons. One series of photos was taken from pretty close to Janus, a moon about a third the diameter of Enceladus that orbits between the F and G rings. And among those, several were taken with the moon sitting in front of Saturn.
Hey amateurs! ESA's running an image processing contest: "Hubble's Hidden Treasures!"
Posted by Emily Lakdawalla on 2012/03/27 04:26 CDT
Here's a newly announced contest that is right up my alley and, I hope, of interest to regular readers of this blog. ESA has just announced "Hubble's Hidden Treasures," a contest to encourage what I've been trying to get people to do for years: trawl through the Hubble archives to find unappreciated tresures of photos and make them pretty for public consumption. They have two categories, one for newbies (who can use image processing tools provided on ESA's website) and one for more serious amateurs (who can use other software).
Snapshots From Space Video: Revealing Jupiter's (Mostly) Unseen Treasures
Posted by Mat Kaplan on 2012/03/18 01:46 CDT | 2 comments
Tens of thousands of Jupiter images were taken by the Voyager spacecraft, but relatively few have been processed to reveal their true beauty and wonder. The latest Snapshots video from Emily Lakdawalla explains why.
Pretty Picture: A snapshot of Voyager 1's departure from Jupiter
Posted by Emily Lakdawalla on 2012/03/13 04:08 CDT
In this week's Snapshots from Space video, I talk about the Voyager 1 images of Jupiter -- how many there are (tens of thousands), and what a challenge they represent for image processors. But, I promise, the effort is worth it. Here's just one example: it's a color, crescent view of Jupiter, taken by Voyager 1 as it departed.
Pretty picture: A study in ringlight
Posted by Emily Lakdawalla on 2012/03/08 02:27 CST
Clearly, this is Saturn, and its rings, and if you look closer you can see a tiny circle, on top of the rings, which is Mimas, and two stars in the background. It should look weird to you that while the rings are bright, Mimas is a black dot. What is happening here? Nearly everything in this picture is lit by light that has not arrived directly from the Sun.

Here are two perfect examples of Voyager 2's amazing untapped treasures.
Snapshots From Space: NASA's Treasure Trove of Unprocessed Images
Posted by Mat Kaplan on 2012/02/27 10:22 CST
The second episode of Emily Lakdawalla's new video series reveals the gigantic library of solar system images captured by NASA spacecraft, and explains why we've seen so few of them. Emily says they're all online, waiting for space geeks to turn them into gold.

More Dawn Vesta approach images: first color views
Posted by Emily Lakdawalla on 2012/02/17 11:37 CST
�On June 30, Dawn stopped thrusting for a full Vestian day -- five hours and 20 minutes -- and just watched the asteroid rotate. But unlike the previous observations, they used all of Dawn's�color filters�to acquire the best-ever color photos of the lumpy world.
Dawn images of Vesta! Released!! For everyone!!!

Here's an awesome picture to start off the week. The data came from Cassini's flyby of Enceladus on January 31, 2011; it was part of Cassini's January 2012 data release.�

Pretty pictures from Cassini's recent Dione flyby
Posted by Emily Lakdawalla on 2011/12/22 11:52 CST
Cassini flew close by Dione on December 12 and, as usual, the close pass provided opportunities for lots of dramatic photos, not just of Dione, but of other moons wandering by in the background.

A presentation providing a correctly scaled, reasonably correctly colored view of the largest bodies in the solar system is made available for use by teachers, professors, and informal educators.
A little fun with Deep Impact deep-sky data
Posted by Emily Lakdawalla on 2011/11/14 05:44 CST
Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.
