Solar physicists have observed the smallest ever coronal mass ejection (CME) - a type of explosion where plasma from the Sun is thrown out into space, sometimes striking the Earth and damaging orbiting satellites. The observation has come as a great surprise to scientists and has turned previous i...

This image maps the magnetic activity of the whole-Sun. It shows a 360 degree of longitude in the Carrington coordinate system normally used for solar observations. The map extent is from south pole to north pole in an equal area projection. The solar equator and each 60 degrees of longitude are mark...

The solar storm of 1859, also known as the Solar Superstorm, or the Carrington Event, was the most powerful solar storm in recorded history. From August 28 until September 2, numerous sunspots and solar flares were observed on the sun. Just before noon on September 1, the British astronomer, Richar...

Some erupt, shooting radiation flares and particles out into space. Forced to observe this dance from afar, scientists use all the t...

A 1976 study published in the journal Nature showed that strange Xenon, which is made in supernova explosions, is present within the composition of the Sun. Those findings by the UMR and Grambling team were largely dismissed. Now, in the March 31 2005 issue of Nature, a Japanese and French team repor...
