Eruption of volcano on Io
Ra Patera, Io's gigantic active volcano, erupted intoa huge cloud of sulfuric acid. The acid rises 60 miles (100 kilometers)of the surface of Io. The height of the cloud is ten times higher thana similar eruption on Earth. Galileo spacecraft took this image on June28, 1996. It was taken from 583,200 miles (972,000 kilometers) away fromthe site of eruption.
The Great Red Spot
This spot is actually a gigantic storm, which has beenswirling around for over 300 years on the planet of Jupiter. The stormcould fit to Earths inside of it. This was taken on June 26, 1996 at adistance of 894,000 miles (1490,000 kilometers).
Ganymede
This image contains ridges, grooves, craters, and someflat surface. This picture is from Uruk Sulcus region of Jupiter's moon,Ganymede. The first flyby of Ganymede by Galileo was made on June 27, 1996. This picture was taken at a distance of 4,468 miles (7,448 kilometers)away from Ganymede. The area in which this image is shot is latitude 10degrees north, longitude 168 degrees west, is about 34x25 miles (55x35 kilometers).
Callisto
This image is of Callisto the farthest away of the fourlarge moons of Jupiter. The image consists of three different picturestaken by three different spacecraft. The spacecraft are Voyager 1 (leftside), Galileo (middle), and Voyager 2 (right side). The two Voyagers tooktheir pictures in 1979. The pictures though left a gap in the middle ofthe moon. The Galileo imaging system took the center picture on September9, 1996. Points of interest include a smooth area in the north and a hugecrater stretching 56 miles (90 kilometers) wide. The crater is named Igaluk.
Io
Jupiter's strangely named moon is a mass with a surfacecovered in active volcanoes. NASA spacecraft Galileo spacecraft took thison June 25, 1996. Varied changes in the land have been seen in the lastpicture some 17 years ago. This picture is taken on the Media Regio areaof Io. The image shows detail of volcanic regions and colored depositson Io. In this image the smallest feature in size you can see is 14 miles(23 kilometers). Io's surface is covered with many volcano deposits, whichhold silicate rock and sulfur-rich compounds. The surface is just coatedwith sulfur dioxide.
Europa
This is two images put together to form, Europa, Jupiter'sicy moon. The structure of Europa is very complex according to the imagetaken. The sun lights overlapping ridges and fractures of Europa surface. Also in the center is a more chaotic structure. Ridge segments, whichare missing, tell us that old material has been replaced with new terrain. Only a couple crater marks can been seen indicating that Europa surfaceis not very old.
