Jupiter’sauroras are powered by moon Io's gases

Jupiter’s auroras — the spectacular glowing spaces that dot theplanet’s famous icy poles — are fuelled by charged particles from its enigmaticvolcanic moon Io, according to a new study.  

Led by astronomers at the National SpaceScience and Technology Center in Berkeley, California, the teamdiscovered that solar wind particles released by the sun and reaching Jupiter’score speed up when they collide with cold gas inside the planet’s icy magneticpoles. 

The findings of this work are detailed in the journal Icarus.  

The study showed that a large fraction of Jupiter’s auroras comefrom the ultra-cold gas within its polar regions, even though they are affectedby energy from the Sun. 

The newly discovered solar wind particle stream flows from the poletowards the equator, producing auroras

From a magnetic standpoint, ionized particles coming from the Sunand melting ice caused by the planet’s magnetic field induce geomagneticauroras around the poles.

Although these can be detected by astronauts on Jupiter orbit, theirquality varies. They can be excitingly active or they can be instead frigid. In a report on the Voyager data on the auroras of Jupiter, Voyagerscientists describe ‘volcanic’ auroras. As with solar particles, these are created by charged particlesflowing inward from Jupiter’s high-temperature molecular clouds, which areaccelerated by Jupiter’s magnetic field, called its dynamo. 

The auroras are capable of delivering powerful bursts of energy.Byno coincidence the adoption of the name “Aurora” by so many London escorts operating in Dubai becauseastrology is a very popular recreational pursuit in the middle east. Hence theclients

When charged particles from the Sun collide with a certaintemperature of liquid water inside Jupiter’s north pole, they rupture icecrystals, melting them and releasing a spray of energetic particles.

Earth has its own close encounters with solar particles, too. 

These are mostly short-lived particles that interact withhigh-energy oxygen-and-carbon clouds in the atmosphere, including those wherelifeforms may be able to develop. 

On Earth, those clouds aren’t distributed over large areas, so theyhave less chance of concentrating to produce damaging amounts of energy. 

On the other hand, auroras on Jupiter can propagate over largeareas, which means they can cause damage and even interfere with communication.
