Scientists Discover New Ring And Other Features At Saturn
Saturn sports a new ring in an image taken by NASA's Cassini spacecraft on Sunday, Sept. 17, during a one-of-a-kind observation. view more (2006-09-21)
Voyager data may reveal trajectory of solar system
Nearly 30 years after launch, the two Voyager spacecraft are still operational and returning useful data. In their early years they produced some of the first close up images of the large outer planets. view more (2006-05-31)
How long is a day on Saturn?
Measuring the rotation period of a rocky planet like the Earth is easy, but similar measurements for planets made of gas, such as Saturn, pose problems. view more (2006-05-04)
UI's Gurnett finds 'lumpy' ionosphere, glimpses of the subsurface of Mars
University of Iowa Space Physicist Don Gurnett and his UI colleagues report that a scientific instrument aboard the European Space Agency's (ESA) Mars Express spacecraft is working perfectly and that its data have so far revealed that Mars' ionosphere - part of the upper atmosphere - is very lumpy and complex, and that the instrument can... view more...

Cassini flies by Saturn's tortured moon Mimas
On its recent close flyby of Mimas (MY-muss), the Cassini spacecraft found the Saturnian moon looking battered and bruised, with a surface that may be the most heavily cratered in the Saturn system. view more (2005-08-08)
Saturn's faint rings share some of their secrets
NASA Cassini spacecraft images of Saturn's diaphanous G and E rings are yielding new clues about their structure and formation. view more (2006-07-06)
Venus mission will hold surprises says U. of Colorado planetary scientist
University of Colorado at Boulder planetary scientist Larry Esposito, a member of the European Space Agency's Venus Express science team, believes the upcoming mission to Earth's "evil twin" planet should be full of surprises. view more (2005-11-03)
Saturn's winds are variable
A team of astrophysicists at the University of the Basque Country has detected, for the first time ever, changes in Saturn's winds. The research has merited front page coverage in the scientific magazine, Nature. The winds blowing around Saturn and Jupiter are special. Unlike those of the rest of the planets, these move in an eastwards direction... view more... (2003-06-09)
Saturn ring spokes may re-appear in July, says new U. of Colorado study
The unusual spokes that appear fleetingly on the rings of Saturn only to disappear for years at a time may become visible again by July, according to a new study spearheaded by the University of Colorado at Boulder. view more (2006-03-17)
Cassini finds 'missing link' moonlet evidence in Saturn's rings
Scientists with NASA's Cassini mission have found evidence that a new class of small moonlets resides within Saturn's rings. There may be as many as 10 million of these objects within one of Saturn's rings alone. view more (2006-03-30)
Predicting the weather on Titan?
Using recent Cassini, Huygens and Earth-based observations, scientists have been able to create a computer model which explains the formation of several types of ethane and methane clouds on Titan. view more (2006-01-24)
Cassini finds more rings highlighted by telltale small particles
Images taken by NASA's Cassini spacecraft, looking in the direction of the Sun, have provided scientists fresh insights into the dynamic nature of the rings and, in particular, the creation of new rings made from tiny particles released from larger bodies. view more (2006-10-12)
Ghostly spokes in Saturn's rings spotted by Cassini
Delighted scientists on the Cassini imaging team will be breaking out the champagne in celebration of the first Cassini sighting of spokes, the ghostly radial markings discovered in Saturn's rings by NASA's Voyager spacecraft 25 years ago. view more (2005-09-19)
Voyager 2 Proves the Solar System is Squashed
NASA's Voyager 2 spacecraft has followed its twin Voyager 1 into the solar system's final frontier, a vast region at the edge of our solar system where the solar wind runs up against the thin gas between the stars. view more (2007-12-11)
Astronomers get first look at Uranus's rings as they swing edge-on to Earth
As the rings of Uranus swing edge-on to Earth - a short-lived view we get only once every 42 years - astronomers observing the event are getting an unprecedented, glare-free view of the rings and the fine dust that permeates them. view more (2007-08-24)
New Cassini image shows "A" ring contains more debris than once thought
Views of Saturn's stunning ring system from above by the Cassini-Huygens spacecraft now orbiting the planet indicate the prominent A ring contains more debris than once thought, according to a new University of Colorado at Boulder study. view more (2006-04-07)
Cassini's doubleheader flybys score home run
Cassini performed back-to-back flybys of Saturn moons Tethys and Hyperion last weekend, coming closer than ever before to each of them. view more (2005-10-03)
Computer simulation predicts Voyager 2 will reach major milestone in space in late 2007-early 2008
Using a computer model simulation, Haruichi Washimi, a physicist at UC Riverside, has predicted when the interplanetary spacecraft Voyager 2 will cross the "termination shock," the spherical shell around the solar system that marks where the solar wind slows down to subsonic speed. view more (2007-11-28)
Space games
Lack of awareness about UK involvement in space science and astronomy missions is widespread, but that could soon change for students in selected schools who are chosen for a test run of a new educational card game featuring scientific satellites. The game, developed by Mr David Smith, of the University of Leicester Space Research Centre, is... view more... (2002-06-11)
Hubble, Keck images show continued turbulence in Jupiter's atmosphere
Increased turbulence and storms first observed on Jupiter more than two years ago are still raging, according to astronomers from the University of California, Berkeley, and the W. M. Keck Observatory in Hawaii, who snapped high-resolution pictures of the planet earlier this month. view more (2008-05-23)
