Jupiter's Great Red Spot ... In Motion

The below animations show Jupiter's Great Red Spot rotating over 20 hours (each time step is separated by 10 hours). The same animation is shown in both color and in blue light only.This massive anti-cyclone is a high pressure storm large enough for three Earths to fit across it. Wind speeds in the storm approach 400 mph (which equals 180 miles per second) and the storm has been present for at least the last 150 years. The images were mapped at 0.1 deg/pixel and span 40 degrees of latitude and longitude.

The animations below were made by using mapped images at 410nm and 673nm to make a quasi-true color movie of the Great Red Spot's motion (far right). The individual images of the blue (410nm) and red (673nm) filters are also shown.

To make the picture move: Place mouse over labels at the left of the image to step through a 3-image animation of the Great Red Spot on Jupiter. Images courtesy of A. Simon-Miller (NASA/GSFC)

These maps span 360 degrees of Jupiter's cloud surface starting at 130 degrees W on the east edge. They span from +60 degrees to -60 degrees in Jupiter's latitude. Images were taken with the Hubble Wide Field Planetary Camera 2. Images courtesy of A. Simon-Miller (NASA/GSFC).

To Jupiter... and Pluto... and Beyond!

The New Horizons Mission has been sending back phenominal images of the Jupiter system. Many images and facts can be obtained from the official New Horizons web site. This stunning image of Io, up close and personal, is just a small example of the potential for visiting solar system objects. Io is Jupiter's largest moon, and volcanicly active.

This dramatic image of Io was taken by the Long Range Reconnaissance Imager on New Horizons at 11:04 Universal Time on February 28, 2007, just about 5 hours after the spacecraft's closest approach to Jupiter. The distance to Io was 2.5 million kilometers (1.5 million miles) and the image is centered at 85 degrees west longitude.

More information about the image can be obtained from the photo caption.

Due to Hubble's distance, it too can image Io, but at a much broader scale. These images were taken with Hubble's Wide Field Planetary Camera 2 on February 14, 2007. The left image, taken in natural color, reveals orange oval deposits of sulfur around the Pele volcano, and other familiar surface features on Io, which is innermost of the Galilean satellites. The ultraviolet image on the right shows a big plume rising above the surface, not far from the north pole. Though Io is no bigger than Earth's geologically dead Moon, Io's interior is kept molten due to the gravitational tug of Jupiter and the other Galilean satellites.
