Probe Shows Jupiter Moon 'Puking' Into Space

Tablizer writes "The New Horizons probe caught the moon Io in the act of 'barfing' into space. A five-frame sequence from the New Horizons probe captured a beautiful plume of ash from Io's Tvashtar volcano. "Snapped by the probe's Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Jupiter earlier this year, this first-ever "movie" of an Io plume clearly shows motion in the cloud of volcanic debris, which extends 330 kilometers (200 miles) above the moon's surface ... The appearance and motion of the plume is remarkably similar to an ornamental fountain on Earth, replicated on a gigantic scale.""

Amazing pics

I'm amazed by this short sequence.
Considering the distance it's a real neat proof of excellent space ship engineering.

Looking at the hight to which the venting reaches this is one hell of a volcano!

Direction of spout

At first I thought the direction of motion of the debri was from right-to-left. However, watching the animation loop for a while, it now appears that it is coming from the middle-to-right center of the plum and spreading out, but below the visible horizon. It is coming up, over the edge as it spreads out.

Bandwidth and in this case, distance from the target. New Horizons required 3 months to return all the data it took during the mission, which included more than just images, but specta and in situ data as well. In addition, the images used to make this movie were taken from a distance of 3.8 million km! The image quality and resolution (~19 km/pixel) is actually much better than we would have gotten at a similar distance from Galileo, Cassini, or Voyager, the previous three missions to observe Io.
