Un tsunami solar de proportii uriase s-a declansat in urma cu putin timp! ATENTIE, la masurile ce trebuiesc luate in regim de urgenta!

 
 •   12 Iul 2013   •  
 
"N-am mai văzut aşa ceva pe suprafaţa Soarelui!" Cât de PERICULOS este fenomenul care s-a întâmplat în urmă cu puţin timp.
 
 
Cercetătorii au descoperit un fenomen inedit pe suprafaţa Soarelui. Este vorba despre un tsunami solar.

Acesta se manifestă prin valuri de plasmă extrem de fierbinte, care emit gaze cu o viteză de aproximativ 400 de kilometri pe secundă.
 
 
Cercetătorii care urmăresc fenomenul spun că este foarte important să cunoaştem toate detaliile acestui tsunami pentru a învăţa cum să ferim Pământul de astfel de situaţii.

Sun Erupts with a CME Toward Earth and Mercury

July 9, 2013

On July 9, 2013, at 11:09 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. 
 
Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory, show that the CME left the sun at speeds of around 375 miles per second, which is a fairly typical speed for CMEs.
 
Earth-directed CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they funnel energy into Earth's magnetic envelope, the magnetosphere, for an extended period of time. The CME’s magnetic fields peel back the outermost layers of Earth's fields changing their very shape. Magnetic storms can degrade communication signals and cause unexpected electrical surges in power grids. They also can cause aurora.  Storms are less frequent during solar minimum, but as the sun’s activity ramps up every 11 years toward solar maximum – currently expected in late 2013 – strong storms occur more frequently.
 
The CME may also pass by the Messenger and Juno spacecraft and their mission operators have been notified. If warranted, operators can put spacecraft into safe mode to protect the instruments from the solar material.
 
In the past, geomagnetic storms caused by CMEs of this strength have usually been mild.

    1. Da, da !
      Cred ca te-ai dilit la mansarda, de ai inceput s-o bagi in amerloaca !
      Parerea mea este ca, riscul de a o lua prin cucuruz, este maxim !

    2. Las' ca pricepi tu...
      Dupa cate te cunosc, puteam scrie si in chineza!
      Oricum, ai remarcat... e de rele; ce rost mai au a fi traduse!
