Solar prominence looks like the Eiffel Tower

By  | 

NASA’s Solar Dynamics Observatory has managed to capture amazing plasma bursts also known as solar prominence that looked like the Eiffel Tower.

SDO notes in a post that the single plume of plasma rose from the surface the Sun, twisted and spun around, all the while spewing streams of particles for over two days from August 17 to 19 before breaking apart. The post notes that the plume at times resembled the Eiffel Tower.

As NASA explains, a solar prominence, which is also called a filament when viewed against the solar disk, is a large, bright feature extending outward from the Sun’s surface. Scientists haven’t still figured out why prominence are formed, but it is known that the prominence are anchored to the Sun’s surface in the photosphere, and extend outwards into the Sun’s hot outer atmosphere, called the corona.

A prominence forms over timescales of about a day, and stable prominences may persist in the corona for several months, looping hundreds of thousands of miles into space.

The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium. The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma.

In the latest video [embedded below] there are quite a few other lesser plumes and streams of particles as well that are visible. The action was observed in a wavelength of extreme ultraviolet light.
