The stellar fireworks came in the form of two solar storms, or coronal mass ejections (CMEs), that are partly directed at Earth and were observed by NASA's Solar and Heliospheric Observatory (SOHO) that orbits our star. CMEs can contain as much as a billion tons of plasma made up of charged particles and thus carry with them their own magnetic fields.
NASA has projected that the massive ejection of ionized gas called plasma will impact Earth by Friday (July 7). When the charged particles within CMEs strike the magnetic field of our planet, the magnetosphere, they can give rise to large disturbances called geomagnetic storms.
These storms can, in turn, disrupt power and communication infrastructure here on the surface of Earth in addition to affecting satellites, which could adversely influence services such as the global positioning system (GPS).
