Forget asteroids: Solar storm could 'cause apocalypse on Earth with just 12 hours warning'
The
government has alarmingly admitted it is "woefully underprepared" for a
major solar storm which could cause plane crashes, train derailments,
huge fires, mass power blackouts and satellite disruption.
A
solar storm follows eruptions of mass and energy from the sun's surface,
including flares, sunspots, and coronal mass ejections which send huge
amounts of X-rays and radiation towards Earth.
Solar storm can
refer to: Solar flare, a large explosion in the sun's atmosphere.
Coronal mass ejection (CME), a massive burst of solar wind, sometimes
associated with solar flares. Geomagnetic storm, the interaction of the
Sun's outburst with Earth's magnetic field.
A coronal mass
ejection (CME) is a massive burst of gas and magnetic field arising from
the solar corona and being released into the solar wind.
Coronal
mass ejections release huge quantities of matter and electromagnetic
radiation into space above the sun's surface, either near the corona
(sometimes called a solar prominence), or farther into the planet
system, or beyond (interplanetary CME). The ejected material is a plasma
consisting primarily of electrons and protons. While solar flares are
very fast, CMEs are relatively slow.
Near solar maxima, the Sun
produces about three CMEs every day, whereas near solar minima, there is
about one CME every five days.
When the ejection is directed
towards Earth and reaches it as an interplanetary CME (ICME), the shock
wave of the traveling mass of solar energetic particles causes a
geomagnetic storm that may disrupt Earth's magnetosphere, compressing it
on the day side and extending the night-side magnetic tail. When the
magnetosphere reconnects on the nightside, it releases power on the
order of terawatt scale, which is directed back toward Earth's upper
atmosphere.
Solar energetic particles can cause particularly
strong aurorae in large regions around Earth's magnetic poles. These are
also known as the Northern Lights (aurora borealis) in the northern
hemisphere, and the Southern Lights (aurora australis) in the southern
hemisphere. Coronal mass ejections, along with solar flares of other
origin, can disrupt radio transmissions and cause damage to satellites
and electrical transmission line facilities, resulting in potentially
massive and long-lasting power outages.
Humans at high altitudes,
as in airplanes or space stations, risk exposure to relatively intense
cosmic rays. Cosmic rays are potentially lethal in high quantities. The
energy absorbed by astronauts is not reduced by a typical spacecraft
shield design and, if any protection is provided, it would result from
changes in the microscopic inhomogeneity of the energy absorption
events.
