Discovery of Saturn's auroral heartbeat
|

|
|
An international team of scientists led by Dr Jonathan Nichols of the University of Leicester has discovered that Saturn's aurora, an ethereal ultraviolet glow which illuminates Saturn's upper atmosphere near the poles, pulses roughly once per Saturnian day. (2010-08-04)

Caltech scientists measure changing lake depths on Titan
|
|
09/09/2010 01:41 AM
|
|
On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake-level changes on Saturn's largest moon, Titan-the only other place in the solar system seen to have a hydrological cycle with standing liquid on the surface.

Man-made aurora to help predict space weather
|
|
09/09/2010 01:41 AM
|
|
For more than 25 years, our understanding of terrestrial space weather has been partly based on incorrect assumptions about how nitrogen, the most abundant gas in our atmosphere, reacts when it collides with electrons produced by energetic ultraviolet sunlight and "solar wind." (2010-06-08)

Early Earth haze likely provided ultraviolet shield for planet, says CU-Boulder study
|
|
09/09/2010 01:41 AM
|
|
A new study shows a thick organic haze that enshrouded early Earth several billion years ago may have been similar to the haze now hovering above Saturn's largest moon, Titan, and would have protected primordial life on the planet from the damaging effects of ultraviolet radiation. (2010-06-04)

|
|
The seemingly serene orb of Saturn is in fact a gas giant with extraordinary patterns of charged particles and rough and tumble roller derbies for rings. (2010-03-19)

Caltech scientists discover fog on Titan
|
|
09/09/2010 01:41 AM
|
|
Saturn's largest moon, Titan, looks to be the only place in the solar system-aside from our home planet, Earth-with copious quantities of liquid (largely, liquid methane and ethane) sitting on its surface. (2009-12-18)

Dark side of a Saturnian moon: Iapetus is coated with foreign dust
|
|
09/09/2010 01:41 AM
|
|
Iapetus is often called Saturn's most bizarre moon, due to its starkly contrasting hemispheres - one black as coal, the other white as snow. (2009-12-11)

Caltech scientists explain puzzling lake asymmetry on Titan
|
|
09/09/2010 01:41 AM
|
|
Researchers at the California Institute of Technology (Caltech) suggest that the eccentricity of Saturn's orbit around the sun may be responsible for the unusually uneven distribution of lakes over the northern and southern polar regions of the planet's largest moon, Titan. (2009-11-30)

ESA spacecraft may help unravel cosmic mystery
|
|
09/09/2010 01:41 AM
|
|
When Europe's comet chaser Rosetta swings by Earth tomorrow for a critical gravity assist, tracking data will be collected to precisely measure the satellite's change in orbital energy. The results could help unravel a cosmic mystery that has stumped scientists for two decades. (2009-11-13)

A Long Night Falls Over Saturn's Rings
|
|
09/09/2010 01:41 AM
|
|
As Saturn's rings orbit the planet, a section is typically in the planet's shadow, experiencing a brief night lasting from 6 to 14 hours. However, once approximately every 15 years, night falls over the entire visible ring system for about four days. (2009-10-26)

Cassini Helps Redraw Shape of Solar System
|
|

|
|
In a paper published Oct. 15 in Science, researchers from the Johns Hopkins Applied Physics Laboratory (APL) present a new view of the region of the sun's influence, or heliosphere, and the forces that shape it. Images from one of the Magnetospheric Imaging Instrument's sensors, the Ion and Neutral Camera (MIMI/INCA), on NASA's Cassini spacecraft suggest that the heliosphere may not have the comet-like shape predicted by existing models.
