This is the first collision of two solar system bodies ever to be observed, and the effects of the comet impacts on Jupiter's atmosphere have been simply spectacular and beyond expectations. Comet Shoemaker-Levy 9 consisted of at least 21 discernable fragments with diameters estimated at up to 2 kilometers. IMPORTANT NOTE: These images are for visualization purposes only.

The Galilean moons should be aligned to Jupiter's equator.This visualization shows jupiter and 63 of its moons. We start close in to Jupiter showing relativly fast moving inner moons that are generally in the same orbital plane including the so called 'Galilean moons': Europa, Io, Ganymede, and Callisto. Other inner moons are: Amalthea, Thebe, Adrastea, and Metis. These inner moons orbit Jupiter as fast as about every 7 hours to about every 17 days. These moons are also relativly close to Jupiter: from around 100 thousand to a couple of million kilometers away.We pull back revealing many smaller moons much farther away (tens of millions of kilometers) in much longer orbits (up to several years). Time speeds up to show the motion of these moons in irregular orbits.

            "description": "This animation illustrates the difference in the rotational period between the Earth and Jupiter. Earth rotates once in 24 hours; whereas, Jupiter rotates more quickly, taking only about 10 hours. This means that Jupiter rotates about 2 1/2 times faster than the Earth. However, Jupiter is about 11 times bigger than the Earth, so matter near the outer 'surface' of Jupiter is travelling much faster (about 30 times faster) than matter at the outer 'surface' of Earth.This visualization was created in support of the Science On a Sphere film called \"LARGEST\" which is about Jupiter. The visualziation was choreographed to fit into \"LARGEST\" as a layers intended to be composited. The 2 animations of Earth and Jupiter are match rendered so that if played back at the same frame rate (say 30 frames per second), the relative rotational speed differences will be accurate. An example composite is provided for reference; in this composite, only a portion of Jupiter is shown so that the relative sizes of the planets are also represented. The composited shot is designed to be repeated around the scienice on a sphere display several times. || ",

            "description": "When the Cassini mission flew by the planet Jupiter in late 2000, a sequence of full disk images were taken of the planet. Assembled with proper spatial and temporal registration, the sequence could produce fourteen distinct images suitable for wrapping around a sphere.But the time steps between images were large and exhibited significant jumping. The solution was to create additional images between the existing set by interpolation. But simple interpolation would not work due to significant changes between the images.To solve this, we interpolated between the images using the velocity vector field of the cloud images. The velocity vector field was computed by performing a 2-dimensional cross-correlation (Wikipedia: Cross-correlation) between the images. This velocity field was checked against Jupiter velocity profiles from the scientific literature and agreement was excellent. With the addition of a simple vortex flow at the location of the Great Red Spot, the interpolation process was used to generate intermediate images, increasing the total number of images from 14 to 220 and resulting in a smoother animation.  The elapsed time between each interpolated frame corresponds to about 1 hour.
