Tsunami solare

[lnessuno]

impressionante



Explanation: Tsunamis this large don't happen on Earth. One week ago, a large solar flare from an Earth-sized sunspot produced a tsunami-type shock wave that was spectacular even for the Sun. Pictured above, the tsunami wave was captured moving out from active region AR 10930 by the Optical Solar Patrol Network (OSPAN) telescope in New Mexico, USA. The resulting shock wave, known technically as a Moreton wave, compressed and heated up gasses including hydrogen in the photosphere of the Sun, causing a momentarily brighter glow. The above image was taken in a very specific red color emitted exclusively by hydrogen gas. The rampaging tsunami took out some active filaments on the Sun, although many re-established themselves later. The solar tsunami spread at nearly one million kilometers per hour, and circled the entire Sun in a matter of minutes.

leggermente old , comunque interessante,
chissà quali potrebbero essere gli effetti

A violent solar explosion sent a dangerous wave of radiation through space late Tuesday, prompting NASA to order the crews of Discovery and the International Space Station to take shelter overnight, according to Local 6 News partner Florida Today.

The solar flare erupted around 9:40 p.m., unleashing enough radiation to disrupt radio communications on Earth and in orbit while endangering astronauts circling 220 miles above the planet.

NASA flight surgeons and agency radiation experts determined that the burst of highly energetic particles approached a limit that made preventative action prudent, Florida Today reported.

Station commander Michael Lopez-Alegria and shuttle skipper Mark Polansky were told to move their crews to the most shielded areas in either spacecraft.

They include the middeck of the shuttle's crew compartment and temporary sleeping quarters in the station's U.S. Destiny science laboratory.

The back ends of the American lab and a Russian command control center at the outpost also were options, the report said

ecco perchè fa così caldo

Cioè ma.....non so se vi rendete conto delle proporzioni (in km) di quel fenomeno.....è qualcosa di pauroso!

l'onda è di dimensioni impressionanti in effetti, se poi consideri che andava ad una tale velocità da fare il giro DEL SOLE in pochi minuti... anche come velocità non è che scherzasse :|
