Saturn's Shockwaves Reach Supernova Force

During a chance encounter with what appears to be an unusually strong blast of solar wind at Saturn, NASA's Cassini spacecraft detected particles being accelerated to ultra-high energies. This is similar to the acceleration that takes place around distant supernovas. "Cassini has essentially given us the capability of studying the nature of a supernova shock in situ in our own solar system, bridging the gap to distant high-energy astrophysical phenomena that are usually only studied remotely," said Adam Masters of the Institute of Space and Astronautical Science, Sagamihara, Japan.

Scientists are particularly interested in "quasi-parallel" shocks, where the magnetic field and the "forward"-facing direction of the shock are almost aligned, as may be found in supernova remnants. The new study, led by Masters describes the first detection of significant acceleration of electrons in a quasi-parallel shock at Saturn, coinciding with what may be the strongest shock ever encountered at the ringed planet.

Since we can't travel out to the far-off stellar explosions right now, the shockwave that forms from the flow of solar wind around Saturn's magnetic field provides a rare laboratory for scientists with the Cassini mission -- a partnership involving NASA, the European Space Agency and the Italian Space Agency -- to observe this phenomenon up-close. The findings, published this week in the journal Nature Physics, confirm that certain kinds of shocks can become considerably more effective electron accelerators than previously thought.

Shock waves are commonplace in the universe, for example in the aftermath of a stellar explosion as debris accelerate outward in a supernova remnant, or when the flow of particles from the sun - the solar wind - impinges on the magnetic field of a planet to form a bow shock.

Under certain magnetic field orientations and depending on the strength of the shock, particles can be accelerated to close to the speed of light at these boundaries. These may be the dominant source of cosmic rays, high-energy particles that pervade our galaxy.

If we could get a space sail in Saturn's shock wave,
we could accelerate it out of the solar system, at
the speed of light.

Reaching a distant star in 4.2 ligth years.

'Hello Centaurus! Earth calling..send message back." 4.2 light years away...

Yes, it does seem the ultra high cosmic particles are generated right here at home.
When did Cassini detect these?

I am willing to bet that Saturn's bow shock turned to face the Leo Constellation from Earth perspective. Earth magnetosphere turned and faced the Leo Constellation last year on March 12-13, 2012 for almost a full day and NASA was caught trying to scrub the data.

Subtract one year and one day from what is characterized as a 'magnetopause reversal' and you have Fukushima, which is just one of a dozen big quake events on the 188-day cycle. There is something coming out of the Leo Constellation that is nudging comets and asteroids from orbit and this is the same black star-like object that turned Saturn's magnetosphere. Gamma ray bursts cannot possibly create this phenomena, because they have short duration. The inner stellar wind and the solar wind render them impotent by the time the reach this far into the inner solar system. Get more information at http://terral03.com/

@Terral03 - You're just another scaremonger, ripping people off with a site focused on mindless assumptions and unproven theories. I have to admit, this new type of FUD is unique though, as it comes sugar coated in huge calculations and formulas that leave the less informed marveling at the author's mathematical glibness.

I hate censorship as much as the next guy, but can't the admin(s) filter such posts, that actually advertise some obscure site enticing you to buy non-existent "knowledge" ?

There are NO bowwaves or shockwaves There ARE Interaction and Contraction by Ions guiding the Magnetich Lines and at the receiving Side of COMING Ions create Contraction of Field THROUGH the Ions and at the back You See the Magnetfield is attracted AWAY from usual position and dilluted ATTRACTED TOWARD the bypassing Ioncloud.
