A Powerful Solar Flare
Explanation: It was one of the
most powerful solar flares in recorded history. Occurring in 2003 and seen across the
electromagnetic spectrum, the
Sun briefly became over 100 times brighter in
X-rays than normal. The day after this
tremendous X 17 solar flare -- and subsequent
Coronal Mass Ejection (CME) --
energetic particles emitted from the explosions struck the Earth,
creating auroras and affecting satellites. The spacecraft that took these frames --
SOHO -- was put in a
turtle-like safe mode to avoid further damage from this and
subsequent solar particle storms. The
featured time-lapse movie condenses into 10 seconds events that occurred over 4 hours. The CME, visible around the central sun-shade, appears about three-quarters of the way through the video, while frames toward the very end are progressively noisier as
protons from the
explosions strike SOHO's LASCO detector. One this day in 1859, the effects of an even more powerful solar storm caused telegraphs on Earth to spark in what is known as the
Carrington Event. Powerful
solar storms such as these may create
beautiful aurora-filled skies, but they also pose a real danger as they can
damage satellites and even power grids across the Earth.
