"Dusty Plasma"  Observed in Enceladus Plume Region?

  Recent findings from NASA’s Cassini mission reveal that Saturn’s geyser moon Enceladus provides a special laboratory for watching unusual behavior of plasma, or hot ionized gas. In these recent findings, some Cassini scientists think they have observed “dusty plasma,” a condition theorized but not previously observed on site, near Enceladus. This image is a [continue reading]

Uranus auroras glimpsed from Earth

For the first time, scientists have captured images of auroras above the giant ice planet Uranus, finding further evidence of just how peculiar a world that distant planet is. Detected by means of carefully scheduled observations from the Hubble Space Telescope, the newly witnessed Uranian light show consisted of short-lived, faint, glowing dots – a [continue reading]

Teamwork: IBEX and TWINS Observe a Solar Storm

On April 5, 2010, the sun spewed a two million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere. As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm that interfered with [continue reading]

Solar Eruptions Cause Sunquakes

A study led by UCL’s Mullard Space Science Laboratory has shown for the first time that sunquakes can be produced during eruptions of magnetic field and charged particles, as the immense magnetic structure blasts off into the Solar System. The results will be presented by Dr Sergei Zharkov at the National Astronomy Meeting 2012 in [continue reading]

Cassini makes simultaneous measurements of Saturn's nightside aurora and electric current system

Since the NASA / ESA Cassini-Huygens spacecraft arrived at Saturn in 2004, astronomers and space scientists have been able to study the ringed planet and its moons in great detail. Now, for the first time, a team of planetary scientists have made simultaneous measurements of Saturn’s nightside aurora, magnetic field, and associated charged particles. Together [continue reading]
