NASA experts have again warned of potential danger to Earth
the explosion of a single large solar storm in 2012, generated more
than 150 million miles away, on the surface of the Sun An extreme solar
activity intense in the coming years are expected increasing levels, this would
cause an unprecedented disaster.
Our energy and communications systems would be seriously
damaged by application of the solar plasma and our comfortable Western life
system, which relies more than ever on technology, would collapse like a house
of cards. Not for the first time NASA made this warning. Two years
ago, released a study that predicted even millions of deaths in 2012 if the sun
discharged its "perfect storm."
Researchers, policy makers and American politicians these
days have gathered in Washington to sharpen the focus on critical
infrastructure protection. The ultimate goal is to improve the human
capacity to prepare, mitigate and respond to weather potentially devastating
space.
"I think we're in a new era in which space weather can
be so influential in our daily lives as ordinary terrestrial weather,"
says Richard Fisher, head of NASA's Heliophysics Division.
In 2012 solar storm 20 times worse than the
"Katrina"
"The sun is waking from a deep sleep and in the coming
years we expect to see much higher levels of solar activity. At the same
time, our technological society has developed an unprecedented sensitivity to
solar storms, "explains the expert. The National Academy of Sciences
of the United States (NAS) published the problem a couple of years ago a major
study funded by the U.S. space agency. It reflected a grim
picture. The twenty-first century civilization is based on high-tech
systems. But these smart energy networks, the GPS navigation, air traffic
control or communications systems can be eliminated by intense sun
tantrum. A phenomenon of this kind could cause economic damages twenty
times stronger than Hurricane Katrina.
Nevertheless, there is a response. NASA believes that
much of the damage can be mitigated if known as accurately as possible the
arrival of a storm, with actions, such as satellites or disconnecting protean
transformers. To this end, the space agency probes, including STEREO, ACE
and SDO provide up to the minute information about what is happening on the Sun
SDO (Solar Dynamics Observatory) is the latest addition to the
fleet. Launched in February, is able to photograph the solar active
regions with unprecedented spectral resolution. Now, scientists can
observe flares in great detail.
