Waves and Small Particles in Ring A: Specially designed Cassini orbits place Earth and Cassini on opposite sides of Saturn's rings, a geometry known as occultation. Cassini conducted the first radio occultation observation of Saturn's rings on May 3, 2005. Three simultaneous r...

Specially designed Cassini orbits place Earth and Cassini on opposite sides of Saturn's rings, a geometry known as occultation. Cassini conducted the first radio occultation observation of Saturn's rings on May 3, 2005. Three simultaneous radio signals of 0.94, 3.6, and 13 centimetre wavele...

Like a special effect from a classic Star Trek episode, this Chandra X-ray telescope image reveals that the rings of Saturn sparkle in X-rays (blue dots in this X-ray/optical composite). The likely source for this radiation is the fluorescence caused by solar X-rays striking oxygen atoms...

Astronomers have discovered 12 new moons orbiting Saturn, bringing its number of natural satellites to 46. The moons are small, irregular bodies - probably only about 3-7km in size (assuming they have a surface albedo of 4%) - that are far from Saturn and take about two years to complete one o...

Two researchers have published their recent findings in the July 23 issue of the Geophysical Research Letters. Their paper is based on data from the Cassini spacecraft radio and plasma wave science instrument. Their study investigates sounds that are not just eerie, but also descriptive of a ph...

Astronomers using the ESA's XMM-Newton telescope has discovered that observing Jupiter's atmosphere may actually give them an insight in to solar activity on the far side of the Sun. It was discovered that Jupiter's x-ray glow is due to x-ray photons from the Sun being reflected back o...

Saturn is approaching "superior conjunction". It will be almost directly behind the Sun and hidden from the Earth on the 25th July. The Cassini spacecraft, in orbit around Saturn, will not be able to send or receive transmissions normally. Regular science data collection has been tempo...

The Cassini spacecraft discovered intriguing dust particles around Saturn's moon Enceladus during its February 17 flyby, and during another flyby on March 9 at an altitude of 500 kilometres. The onboard co...

In a few days time the planet Saturn will be the closest to the planet Earth for 2006 - It will be only 1215.9 million kilometres away. Saturn appears as a bright yellowish star, low to the east-northeast as evening twilight is ending. It is the brightest object in the constellation of Cancer. [i...

Filter tips for observing Saturn: A #82A Light Blue filter is a popular filter to highlight low contrast features on the planet. A #11 Yellow-Green filter (78% transmission) is also a nice general filter to observe Saturn. The filter will increase the contrast of any dark surface detail on the plane...

One of Saturn's rings is flaring and fading in a very strange fashion. When Voyager 1 visited the planet in 1980, the ring was faint, but it sparkled with bright spots. By the time the Cassini mission arrived in 2004, the spots were gone - but the ring as a whole had grown twice as bright. The F ring has been...
