(CMEs), can sometimes contain a billion tons of matter, which has enough power to potentially wipe out all man-made technology, if it hits Earth.
The Sun is often racked by short-term violent events such as flares and coronal mass ejections
(CMEs) but these two phenomena are often confused.
According to the Discovery Channel, solar storms occur when the sun emits huge bursts of energy in the form of solar flares and coronal mass ejections
Occasionally, eruptions called coronal mass ejections
occur, with higher density, energy and speed of the ejected particles.
A team from a consortium of UK universities, including the University of Sheffield and Queen's University Belfast, observed the huge coronal mass ejections
in extremely high detail using the Swedish Solar Telescope on the island of La Palma, in The Canaries.

The data gathered by Metis will allow scientists to completely characterise remotely the two most important plasma components of the corona and the solar wind (electrons and protons) and answer fundamental questions about the origins of the fast and slow wind, the sources of solar energetic particles, and the eruption and early changes in coronal mass ejections
Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections
Last year a report by the Department for Business, Innovation and Skills, in the United Kingdom, reported that solar activity can produce "x-rays, high-energy particles and coronal mass ejections
The aurora borealis is caused by eruptions on the surface of the sun - technically known as coronal mass ejections
- and recent solar activity has been unexpectedly strong, resulting in the biggest solar storm to reach the Earth for two decades.
Among specific topics are minima of the Centennial Gleissberg Cycle and the heliospheric boundary, characteristics of magnetic flux ropes from the sun to the heliosphere, electron acceleration and spectral hardening of continuum emission in solar flares, Voyager 1 measurements and theoretical modeling of magnetized plasma near the heliopause, and analyses of the evolution and interaction of multiple coronal mass ejections
and their shocks in July 2012.
That is to say that even out to 5 million miles from the sun, giant solar storms or coronal mass ejections
can create ripple effects felt through the corona.
