Amazing Solar Prominence video

3 posts in this topic

APOD has a wonderful time-lapse of a solar prominence erupting on their site today:

http://antwrp.gsfc.nasa.gov/apod/ap100510.html

Explanation: Sometimes part of the Sun can just explode into space. These explosions might occur as powerful solar flares, coronal mass ejections, or comparatively tame eruptive solar prominences. Pictured above is one of the largest solar prominence eruptions yet observed, one associated with a subsequent coronal mass ejection. The prominence erupted last month and was recorded by several Sun-sensing instruments, including the recently launched Solar Dynamics Observatory (SDO). The above time lapse sequence was captured by SDO and occurred over a few hours. In recent months, our Sun has becoming increasingly active, following a few years of an unusually dormant solar minimum. Over the next few years our Sun is expected to reach solar maximum and exhibit a dramatic increase in sunspots and all types of solar explosions.

As you watch the movie, keep in mind that the diameter of the Sun is a little over 100 times the diameter of the Earth, which means that the twisting column of plasma that gets ejected from the surface is probably wider in diameter than the Earth itself, and many times longer.

It is believed that these occur when bunched up magnetic field lines within the sun explosively protrude through the surface. Plasma is electrically conducting, so the flow of the plasma is guided along the twisting of the field lines.

Enjoy.

Thanks for that, Carlos. Nature is so fantastic.
