The Sun sported a very long filament

 
 
 
 
 
 
The Sun sported a very long filament (over 30 times the size of Earth) that angled diagonally across its surface for over a week (July 31 - Aug. 6, 2014). Filaments are clouds of cooler gas suspended above the Sun's surface by magnetic forces. They are notoriously unstable and often break apart in just hours or days. So far, this one has held together as it rotated along with the Sun for over a week. The images were taken in the 193 Angstrom wavelength of extreme ultraviolet light and were tinted red instead of its usual brown hue
 
 
 
 El sol lucía un filamento muy largo (más de 30 veces el tamaño de la Tierra) que un ángulo diagonal a través de su superficie durante más de una semana (julio 31 a agosto 6, 2014). Los filamentos son nubes de gas más frío suspendidos por encima de la superficie del Sol por fuerzas magnéticas. Ellos son notoriamente inestables y con frecuencia se rompen en sólo unas horas o días. Hasta el momento, ésta se ha mantenido unida ya que gira junto con el Sol durante más de una semana. Las imágenes fueron tomadas en el 193 Angstrom longitud de onda de la luz ultravioleta extrema y se tiñen de color rojo en lugar de su color marrón habitual.
