Jupiter Moon Movie
29.03.2007

South is toward the top in this frame from a stunning movie featuring Jupiter and moons recorded last Thursday from the Central Coast of New South Wales, Australia. In fact, three jovian moons and two red spots are ultimately seen in the full video as they glide around the solar system's ruling gas giant.

Europa s Freckles
1.11.2002

Europa, one of Jupiter's large Galilean moons, may well posses an ocean of liquid water hidden beneath its icy surface -- and so holds the tantalizing possibility of life. In this image, constructed with...

Jupiter, Saturn and Messier 45
22.03.2001

Brilliant Venus falls out of the evening sky as March ends, but Jupiter and Saturn remain well up above the western horizon. Jupiter blazes forth above and to the left of a slightly fainter Saturn in this telephoto picture taken on January 19th.

Jupiter s Great X Ray Spot
1.03.2002

The Solar System's largest planet, gas giant Jupiter, is famous for its swirling Great Red Spot. In the right hand panel above, the familiar giant planet with storm system and cloud bands is shown in an optical image from the passing Cassini spacecraft.

A Sharper View of a Hazy Giant
6.11.2008

This dramatic image of Jupiter is touted as the sharpest picture of the entire gas giant ever taken from the ground. The picture was made using a prototype instrument known as MAD (Multi-conjugate Adaptive optics Demonstrator) mounted on one of the European Southern Observatory's 8-meter diameter Very Large Telescope units in Chile.

Jupiters Rings Revealed
16.09.1998

Why does Jupiter have rings? Jupiter's rings were discovered in 1979 by the passing Voyager 1 spacecraft, but their origin has always been a mystery. Recent data from the Galileo spacecraft currently orbiting Jupiter now confirms that these rings were created by meteoroid impacts on small nearby moons.

Jupiter and Venus at Sunrise
8.11.2004

What are those bright objects in the morning sky? Early morning dog walkers, among many others across our world's Northern Hemisphere, have likely noticed tremendously bright Venus hanging in the eastern sky just before sunrise. Looking a bit like an approaching airplane, Venus holds its place in the sky and never seems to land.

Jupiter Eclipsing Ganymede
6.01.2009

How hazy is Jupiter's upper atmosphere? To help find out, astronomers deployed the Hubble Space Telescope to watch Jupiter eclipse its moon Ganymede. Although Ganymede circles Jupiter once a week, it usually passes above or below the planet, so that a good eclipse occurs more rarely.

Io s Surface: Under Construction
19.10.2002

Like the downtown area of your favorite city, the roads you drive to work on, and any self-respecting web site ... Io's surface is constantly under construction. This moon of Jupiter holds the distinction of being the Solar System's most volcanically active body -- its bizarre looking surface continuously formed and reformed by lava flows.

Jupiter from Voyager
18.07.1999

This picture of the planet Jupiter was taken by the Voyager 1 spacecraft as it passed the planet in 1979. Jupiter, a gas giant planet with no solid surface, is the largest planet in the Solar System and is made mostly of the hydrogen and helium.
