Solar storms happen when the sun’s
magnetic-field lines bend and break, releasing a considerable amount of
plasma and magnetic storms damaging satellites in spaces.
NASA has now developed new 3D models which show how solar eruptions send shock waves through space.
The new 3D view "confirmed
long-held theoretical predictions of a strong shock near the CME nose
and a weaker shock at the sides," NASA officials said in a recent
statement.
Their findings, published Feb. 13 in the Journal of Space Weather and Space Climate, also revealed the density of the plasma around the shock, as well as the speed and strength of the energized particles unleashed by the sun.
The statement also read: "Much the way ships from bow waves as they move through water, CMEs set off interplanetary shocks when they erupt from the sun at extreme speeds, propelling a wave of high-energy particles.
"These particles can spark space weather events around Earth, endangering spacecraft and astronauts."
The US National Oceanic and Atmospheric Administration (NOAA), who spotted the solar storm using two NASA satellites, said: “A minor geomagnetic storm watch is now in effect for the 14 and 15 March 2018. Aurora may be visible at high latitudes.”
The storm will hit the Northern hemisphere and could result in the Northern Lights being as far south as Scotland.
But scientists have also warned how the solar storm could also affect GPS navigation systems and mobile phone signals tomorrow.
Solar winds, which are a stream of particles from the sun, can heat the Earth’s outer atmosphere, causing it to expand.
This can affect satellites in orbit, potentially leading to a lack of GPS navigation, mobile phone signal and satellite TV such as Sky.

A SOLAR Storm is set to hit the Earth tomorrow as an explosion on the surface of the Sun blasted an army of solar particles and plasma, NASA has warned.
NASA has now developed new 3D models which show how solar eruptions send shock waves through space.
The
new models will also improve space weather predictions which would help
with the prevention of space-crafts and astronauts being endangered in
space.
