Latest Magnetosphere of Jupiter Stories
On Earth, bursts of particles spewed by the Sun spark shimmering auroras, like the Northern Lights, that briefly dance at our planet's poles. But, on Jupiter, there's an auroral glow all the time, and new observations show that this Jovian display sometimes flares up because of a process having nothing to do with the Sun.
Data gathered by ESA's Cluster mission suggests that high-energy particles which fill cavities within the Earth's magnetic field are accelerated locally within the cusps themselves as they cross through areas characterized by different electric potential.
High speed plasma flows, often referred to as jets, are extremely common across the Universe.
GREENBELT, Md., Oct. 27 /PRNewswire-USNewswire/ -- The magnetometers developed at NASA's Goddard Space Flight Center in Greenbelt, Md., for the Juno mission to Jupiter were delivered recently to Lockheed Martin in Denver, Colo.
Besides displaying the most spectacular volcanic activity in the solar system, Io causes auroras on its mother planet that are similar to the Northern Lights on Earth. The auroral emissions linked to the volcanic moon are called the Io footprint.
ESAâ€™s Mars Express spacecraft has for the first time ever detected an aurora on Mars. This aurora is of a type never previously observed in the Solar System.
