Scientist Warns 'Solar Super-Storms' Are Inevitable and a Significant Threat
by Activist PostIn this month's issue of World of Physics , Ashley Dale of the University of Bristol warns of " catastrophic "and" lasting "impact of" solar super-storms "and the dangers they face if the threat continues to go unnoticed .
Dale, who was a member of a group international work - known as SolarMAX - created to identify the risks of a solar storm and how its impact could be minimized, it explains how only a matter of time before an exceptionally strong solar storm is propelled toward Earth is. such a storm could wreak havoc on our communication systems and power supplies, paralyzing vital services such as transportation, health and medicine.
"Without energy, people would have difficulty feeding their cars at petrol stations get money from ATMs or pay online. water and sewage systems would be affected as well, which means that health epidemics in urban areas quickly would take a grip, with diseases that we thought they had left behind centuries before returning, "writes Dale.
Solar flare NASA gif solar storms are caused by violent eruptions on the sun's surface and are accompanied by coronal mass ejections (CME). CMEs are the most energetic events in our solar system and involve huge bubbles of plasma and magnetic fields being thrown from the sun's surface into space.
CMEs are often preceded by a solar flare -. a massive release of energy from the sun in the form of gamma rays, X-rays, protons and electrons
a super solar storm occurs when a CME enough tears of magnitude in the magnetic field surrounding the Earth and ripping apart. Such an event could induce huge waves of electrical currents in the ground and overhead transmission lines, causing widespread power outages and severely damaging critical electrical components.
The largest ever the solar super storm on record occurred in . 1859 and is known as the Carrington Event, named after astronomer Richard Carrington English who saw the previous solar flare
This massive CME launched about 1,022 kJ of energy - the equivalent of 10 million Hiroshima bombs that They explode at the same time - and tossed around a billion kilograms of charged particles toward Earth at a speed of up to 3000 km / s particles. Its impact on the human population, however, was relatively benign as our electronic infrastructure at the time amounted to no more than about 200,000 km of telegraph lines.
Dale makes it clear that these events are not only a threat but inevitable. In fact, NASA scientists have predicted that the Earth is in the path of a Carrington-level event every 150 years on average - which means that at present five years late - and that the probability of a place in the next decade is as high as 12%.
the 40-strong international team of scientists SolarMAX gathered at the International Space University in Strasbourg, France, last year to identify the best ways to limit damage potential of a super solar storm.
a sub-group of scientists concluded that advanced prediction of space-time is the best solution, which could be achieved by sending a set of 16 satellites bucket lunch box size in orbit around the Sun This network could take about a week in advance of where, when and how solar storms magnitude will take place, providing enough to disconnect the lines vulnerable energy time, satellites redirect, plans land and start national recovery programs.
own solution Dale is the design of spacecraft and satellites, so that sensitive instruments on board are better protected surges again in radiation storms solar. Suggests the redistribution of existing internal architecture of a vessel so that sensitive payloads are surrounded by material not sensitive bulk such as polyethylene, aluminum and water.
"As a species, we has never been more vulnerable to the volatile state of mind of our nearest star, but it is within our ability, skill and experience as human beings to protect ourselves, "says Dale.
