Latest Coronal mass ejection Stories
The natural magnetic bubble surrounding the Earth known as the magnetosphere could be an essential part of what makes our planet habitable, according to new research investigating the impact of solar eruptions on the atmosphere of Venus.
The Sun undergoes a type of seasonal variability with its activity waxing and waning over the course of nearly two years, according to new research led by NCAR.
Our Sun goes through a few activity cycles and a new study has identified one such cycle that is almost seasonal in nature. According to the report, published in the journal Nature Communications, the nearly two-year cycle appears to be caused by shifts in the bands of powerful magnetic fields in each solar hemisphere. These bands also aid in shaping and approximately 11-year solar cycle that is part of a lengthier cycle that lasts approximately 22 years.
An unusual comet was spotted by the NASA/ESA Solar and Heliospheric Observatory (SOHO) as it travelled near the sun late last week, and unlike most other comets that make such a voyage, this one actually lived to tell the tale.
The British Geological Society issued a geomagnetic alert regarding incoming atmospheric disturbances resulting from recent Coronal Mass Ejections from the sun, projected to arrive at Earth on
Understanding vast systems in space requires understanding what's happening on widely different scales. Giant events can turn out to have tiny drivers -- take, for example, what rocked near-Earth space in October 2003.
An area of intense and complex magnetic fields known as an active region rotated into view on October 18, growing into the largest phenomenon of its kind in more than two decades and producing 10 significant solar flares.
Those who study Earth's weather have a luxury of data points to study. Compared to this, the study of space weather – including CMEs – is a much younger science, with far fewer observatories available.
On July 23, 2012, a massive cloud of solar material erupted off the sun's right side, zooming out into space. It soon passed one of NASA's Solar Terrestrial Relations Observatory, or STEREO, spacecraft, which clocked the CME as traveling between 1,800 and 2,200 miles per second as it left the sun.
