Scientists use data to create models of solar storms—violent, dangerous, and more powerful than anything on Earth.

Transcript (English)

- [Narrator] Solar storms are a serious threat to our high-tech lives in the 21st century. The race is on to predict when and where the next one will strike. In September 2006, Japan launches the Hinode satellite. Its three-year mission is to map the sun's complex magnetic fields. The information it sends back could prove key to forecasting solar storms. Hinode orbit's 370 miles above Earth. Its camera peers straight into the sun's atmosphere. It returns the clearest pictures ever of the sun's surface. In December 2006, Hinode captures this groundbreaking footage. A magnetic arc snaps, and a huge flare erupts. It blasts into the solar system at more than a million miles an hour. Karel Schrijver uses data from Hinode to generate the first computer model of a solar storm before it erupts, a detailed map of the sun's complex magnetic fields.

- What drives these large solar flares is the magnetic field, and specifically it's electrical currents running through the magnetic field. So each one of these strands is essentially an electrical current prefabricated in the interior of the sun, breaking through the surface and becoming visible, and then ready to power a flare.

- [Narrator] Where the magnetic fields intertwine the closest the currents are strongest. Schrijver replicates these electrical currents in three dimensions.

- [Karel] If we tilt this, we can suddenly see that these electrical currents come up from one place, go up by something like 15, 20,000 kilometers above the solar surface and come down again.

- [Narrator] The model shows a red river of energy equal to a billion atom bombs. When the flare erupts, it releases that energy in seconds.

- The amount of energy that goes off in this flare is simply astounding. It's the equivalent of a million times a million atomic bombs going off at the same time.

- [Narrator] Before, a red river of current thicker than the Earth. After, almost nothing.

Transcripción (Español)

- [Narrador] Las tormentas solares son una amenaza seria para nuestras vidas de alta tecnología en el siglo XXI. La carrera está en marcha para predecir cuándo y dónde golpeará la próxima. En septiembre de 2006, Japón lanza el satélite Hinode. Su misión de tres años es mapear los complejos campos magnéticos del sol. La información que envía de regreso podría ser clave para pronosticar tormentas solares. Hinode orbita a 370 millas sobre la Tierra. Su cámara mira directamente a la atmósfera del sol. Devuelve las imágenes más claras de la superficie del sol. En diciembre de 2006, Hinode captura este metraje innovador. Un arco magnético se rompe y una enorme llamarada estalla. Se lanza al sistema solar a más de un millón de millas por hora. Karel Schrijver utiliza datos de Hinode para generar el primer modelo computarizado de una tormenta solar antes de que estalle, un mapa detallado de los campos magnéticos del sol.

- Lo que impulsa estas grandes llamaradas solares es el campo magnético, y específicamente son las corrientes eléctricas que atraviesan el campo magnético. Así que cada uno de estos hilos es esencialmente una corriente eléctrica prefabricada en el interior del sol, rompiendo la superficie y volviéndose visible, y luego lista para alimentar una llamarada.

- [Narrador] Donde los campos magnéticos se entrelazan, las corrientes son más fuertes. Schrijver replica estas corrientes eléctricas en tres dimensiones.

- [Karel] Si inclinamos esto, podemos ver de repente que estas corrientes eléctricas surgen de un lugar, suben unos 15, 20,000 kilómetros por encima de la superficie solar y vuelven a bajar.

- [Narrador] El modelo muestra un río rojo de energía igual a mil millones de bombas atómicas. Cuando la llamarada estalla, libera esa energía en segundos.

- La cantidad de energía que se libera en esta llamarada es simplemente asombrosa. Es el equivalente a un millón de veces un millón de bombas atómicas explotando al mismo tiempo.

- [Narrador] Antes, un río rojo de corriente más grueso que la Tierra. Después, casi nada.
