A prominence is a large, bright feature extending outward from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the ...

This prominence on July 24, 1999 was particularly large and looping, extending over 35 Earths out from the sun. ... Sometimes in complex sunspot groups, abrupt, violent explosions from the sun occur. These are called solar flares. Solar flares are thought to be caused by sudden magnetic field changes in areas where the sun...

Prominences and plages are structures that occur above the photosphere of the Sun. Plages are bright cloud-like features found around sunspots that represent regions ... The left image below shows a prominence on the edge of the Sun photographed in H-alpha light by the Big Bear Solar Observatory at 16:17 UT on October 3rd,

Huge sweeping prominence, ... Sun's magnetic storms are illustrated here. The Earth's magnetic field is distorted but shields most of the effect of Sun's storms. Sun's storms occur quite frequently and a really strong burst from the Sun directed towards Earth may damage satellites, disrupt communications and even cause blackout.

Sun Prominence; This image was acquired from NASA's Skylab space station on December 19, 1973. ... These eruptions occur when a significant amount of cool dense plasma or ionized gas escapes from the normally closed, confining, low-level magnetic fields of the Sun's atmosphere to streak out into the interplanetary medium,

Charged particles are attracted by magnetic fields, so when you have a strong magnetic field loop near the surface of the sun, the ionized particles get trapped in it and you can get a prominence. ... These temperatures which allow fusion to occur are at about one million degrees, a temperature very difficult...

Flares occur when these field lines meet and "reconnect", ... Dramatic prominences can sometimes be seen looming just beyond the edge of the sun. A solar prominence is a cloud of solar gas held just above the surface by the Sun's magnetic field. The Earth would easily fit below the prominence on the left.

Explanation: A huge eruptive prominence is seen moving out from our Sun in this condensed half-hour time-lapse sequence. Ten Earths could easily fit in the "claw" of this seemingly solar monster. This large prominence, though, is significant not only for its size, but its shape.

On February 12, the sungazing SOHO spacecraft captured this dramatic image of a magnificent prominence above the Sun's limb. Seen at the lower right, streams of relatively cool dense plasma were lofted along looping magnetic field lines extending outward about 30 times the diameter of planet Earth.
