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...

If you hadn’t noticed there are 2 huge sunspots visible on the face of the Sun. One is as large as the planet Jupiter in size and it seems to be growing. [img]http://sohowww.nascom.nasa.gov/data/www.esa.int/mdi...

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...

A layer deep in the solar atmosphere can be used to estimate the speed of the solar wind, a stream of electrified gas that constantly blows from the Sun. Estimating the speed of the solar wind will improve space weather fore...

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...

A Big Surprise from the Edge of the Solar System NASA's Voyager probes are truly going where no one has gone before. Gliding silently toward the stars, 9 billion miles from Earth, they are beaming back news from the most distant, unexplored reaches of the solar system. Mission scientists say the prob...

Something New On the Sun: SDO Spots a Late Phase in Solar Flares The sun's surface dances. Giant loops of magnetised solar material burst up, twist, and fall back down. 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...

Giant columns of solar material - made of gas so hot that many of the electrons have been scorched off the atoms, turning it into a form of magnetized matter we call plasma - leap off the sun's surface, jumping and twisting. So...
