Sunday Bonus – Enceladus

Confession time -- when I was at Dragon*Con, I attended a talk in the Science section about the latest findings from NASA's Saturn orbiter, Cassini, which was pretty amazing. And while technically science stuff is not really what I do here on, you can't have sci-fi (which DOES fit) without the sci.

Plus, this is a totally cool image, so nyah:

For a fuller explanation of what you're seeing (hint, the moon is not the Death Star trying to escape on full thrusters -- "That's no moon!"), check out the Bad Astronomer blog on In a nutshell, this is Enceladus, one of Saturn's moons, ejecting a bunch of vapor out of volcanoes on one side. The ejecta ultimately forms the majority of Saturn's E ring.

The person giving the lecture at Dragon*Con was on the Cassini team responsible for these images and she actually talked a fair bit about Enceladus. The team running the magnetic field detection equipment got some interesting data on one pass indicating something funny going on with that side of the moon, so they decided to do a relatively low-altitude fly-through with the visual cameras to see what was going on. They were delighted at the images they got back, showing these huge volcanic ejections.

It was really neat to listen to actual scientists working on actual projects out there on the very edge of explored space, and completely humbling as well. The stuff we're able to do nowadays is just mind blowing.

    I’ve always been interested in the things of space and spacey things. Thanks for sharing this, seems we’re slowly expanding our knowledge, firstly of our own solar system, which should be a top priority, then finally the the whole expanse of the universe.

    I hate to bring the intellectual level of the conversation down so far, but Saturn’s rings are made of Moon Farts? Or more specifically, Moon Sharts?

    Only one. The rest are comet burps.

    Read a scholarly journal on this. Fascinating really the way the planet gets squeezed by the immense gravity of Saturn to create the geysers which shoot into space.

    Come to California’s JPL (or your local space center) on their Open House day to see where tax dollars go — e.g., hxxp://

    Humanity has such a long way to go to unravelling, not so much the secrets, but the day-to-day of the universe at large!
