A solar tsunami is a rare astronomical phenomenon, caused by the magnetic explosion in the sun. The sun has spurted a huge cloud towards the earth which is full of electronic ions. The planet was hit by a “Solar Tsunami” racing 93 million miles across the space. Scientists have warned that the earth could be hit by a wave of violent space storm(Coronal Mass Ejection) after a massive explosion on the sun. This huge explosion could shut down the global communication and the satellites might get destroyed. “These eruptions occur when immense magnetic structures in the solar atmosphere lose their stability and can no longer be held down by the Sun’s huge gravitational ...view middle of the document...
It has suddenly grabbed the attention of the inhabitants of the third planet from the sun as the news of the waves heading towards earth. However, solar tsunami would just be limited to blackouts, disruption in communication systems and a rather desirable effect of brighter auroras or the northern lights. It is a tsunami-like shock wave that forms on the Sun. These waves generally roll across the hot surface of the Sun destroying or sweeping away filamentary material. These waves are infrequent yet very powerful. Technical name ‘fast- mode magneto hydro dynamical wave’. It is also referred to as ‘MHD wave’. It is also called moreton wave.
The sun, which is approximately 108 times the size of the earth, is just waking up from a period of record-breaking inactivity during an 11-year cycle set to peak in 2020. The CME clouds, usually emitted from the sun over several hours, can carry up to 10 billion tons of plasma. They usually move away from the sun at about a million miles per hour, allowing them to travel 93 million miles to Earth in only three to four days, according to a NASA press release. These kinds of eruptions are one of the first signs that the Sun is waking up and heading towards another solar maximum expected in the 2020 time frame.
Structure of the Sun:
CORONAL MASS EJECTION:
A coronal mass ejection (CME) is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space. 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, but may contain small quantities of heavier elements such as helium, oxygen, and even iron. It is associated with enormous changes and disturbances in the coronal magnetic field. When the ejection is directed towards the Earth and reaches it as an interplanetary CME (ICME), the shock wave of the traveling mass of Solar Energetic Particles causes a geomagnetic stormthat may disrupt the 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 poweron the order of terawatt scale, which is directed back toward the Earth’s upper atmosphere.
Sunspots – dark areas on the solar surface – are as large as our entire plant and yet form only small eddies along colossal plasma rivers along the sun’s corona (its outermost layer) where strong magnetic fields constantly shift. When groups of these planet-sized spots converge, complex solar-magnetic fields collide and release solar flares, intense sparks of magnetic energy violently spat into the cosmos. The solar flares are the planetary system’s largest explosive events, releasing more energy in the...
