Comet Garradd in 3D (sort of)

Posted by Emily Lakdawalla on 2011/08/12 12:52 CDT

Amateur astronomer Patrick Wiggins sent me this neat little animation of comet Garradd moving against background stars through an hour's worth of observing. I'm not any kind of astronomer but if I were I think I would get a kick out of looking at things that appear to move within one night of watching -- asteroids, comets, Jupiter's spots. I'm impatient that way.

What I see in the first high-res Dawn images of Vesta

Posted by Emily Lakdawalla on 2011/08/02 11:22 CDT

I had to wait until the kids were in bed and the husband fed last night before I finally had time to sit down and really look at the Dawn images of Vesta. And I still hardly knew where to begin. This brand new world is just so different than others I've seen.

Pretty movie: Everything in the Saturn system is in motion!

Posted by Emily Lakdawalla on 2011/07/26 06:28 CDT

A few weeks ago a producer for a public television space documentary asked me if I knew of any cool Cassini animations and my answer was, "Ooh, what a great excuse to have some fun digging around in the Cassini data archives." Here is the most fun animation I came up with in response to the request.

Vesta does a Hyperion impression

Posted by Emily Lakdawalla on 2011/07/21 06:25 CDT

Maybe it's my own peculiar variant of pareidolia, but every time I see a new image of Vesta I'm reminded of some different other lumpy body in the solar system. In the image released just now by the Dawn team, taken from 10,500 kilometers away, I'm seeing Hyperion.

Cassini animations: Rhea and Dione and Titan

Posted by Emily Lakdawalla on 2011/06/28 04:12 CDT

I've been mucking about in the Cassini data archives (as I often do when procrastinating) and unearthed a neat, if short, mutual event sequence of two crescent moons passing by each other.

Cassini finally catches Helene

Posted by Emily Lakdawalla on 2011/06/20 04:41 CDT

Cassini has finally achieved gorgeous global imaging of Helene with a spectacular flyby on Saturday, in which they got Helene to pose prettily for the camera from beginning to end of the encounter. And what a wacky, wacky world Cassini has revealed Helene to be!!

Some recent pictures of Saturn's northern storm

Posted by Emily Lakdawalla on 2011/02/07 04:35 CST

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.

Animation of Phobos rotating from recent Mars Express flyby images

Posted by Emily Lakdawalla on 2011/01/25 10:18 CST

Daniel Macháček has colorized some terrific images of Phobos and run them through some morphing software to make a seamless animation that appears to show Phobos rotating before you.

Two fine color Cassini animations: Prometheus rotating, Tethys and Dione dancing

Posted by Emily Lakdawalla on 2011/01/20 11:23 CST

Daniel Macháček has reached into the dark side of Prometheus and pulled out an incredible amount of detail where the potato-shaped moon is illuminated by Saturnshine. He produced an animation that morphs among the three sets of four-filter color images that Cassini snapped during the flyby.

2010 JL33: How to see an asteroid from quite a long way away

Posted by Emily Lakdawalla on 2011/01/13 11:42 CST

A terrific set of Goldstone radar images of a good-sized near-Earth asteroids named 2010 JL33 was posted to the JPL website yesterday. They also posted a movie version but something about these pixelated radar image series absolutely begs for them to be displayed as an old-school animated GIF, so I made one.

Solar eclipses from space: Hinode and SDO

Posted by Emily Lakdawalla on 2011/01/06 11:33 CST

Two spacecraft that keep their ever-watchful eyes on the Sun -- NASA's Solar Dynamics Observatory (SDO) and JAXA's Hinode -- were doing their thing, when something large wandered past: the Moon.

Posted by Emily Lakdawalla on 2011/01/05 11:38 CST

These two movies were posted to the JPL website a couple of weeks ago, and they are just amazing.

How Mars Express' orbit shifts with time

Posted by Emily Lakdawalla on 2011/01/04 11:02 CST

While I was writing yesterday's blog entry on Mars Express' Phobos flybys I realized that I didn't understand Mars Express' orbit very well. So I sent an inquiry to the Mars Express blog, which they answered in a blog entry today.

Quaoar: A rock in the Kuiper Belt

Posted by Emily Lakdawalla on 2010/04/01 12:48 CDT

The paper I'm writing about today, "Quaoar: a Rock in the Kuiper Belt," is based upon seven sets of Hubble Space Telescope WFPC2 observations of Quaoar and its recently-named moon, Weywot.
