つい先日には大雪に見舞われ、思わず太陽のありがたみも忘れてしまいそうな肌寒い日々が続いている。そんな中、NASAが先日公開した新しい動画は、太陽の荘厳な美しさを余すところなく見せつけてくれる。
この動画は、2010年から太陽を観察しつづけている太陽観測衛星、ソーラー・ダイナミクス・オブザーバトリーによって撮影された。10の異なる波長を用いることで、燃え盛る炎の中に広がる黒点、太陽の輪郭を彩るコロナ、表面から吹き出すフレアの激しい動きまで詳細に捉えている。
動画のBGMには、アメリカのミュージシャン、モービー・グラティスの音楽が使われており、神々しい美しさをたたえた太陽への畏怖を増幅させる。

Solar Flare Myths Explained
MYTH: Solar flares have no effect on Earth.(01 of09)
REALITY: Solar flares can release electromagnetic radiation that\'s strong enough to disrupt electric power grids, satellites, GPS, and radio communications. \n\nPictured: Coronal mass ejection as viewed by the Solar Dynamics Observatory on June 7, 2011. (credit:NASA/SDO)
MYTH: A solar flare could kill us all.(02 of09)
REALITY: Only a tiny fraction of the energy liberated by a solar flare reaches the Earth, because we\'re protected by our planet\'s atmosphere. \"We have a very long record that shows that even the strongest flares can\'t blow out the atmosphere,\" Antti Pulkkinen, a research scientist at NASA\'s Goddard Space Flight Center, told CNN.\n\nPictured: A solar eruptive prominence as seen in extreme UV light on March 30, 2010 with Earth superimposed for a sense of scale.\n (credit:NASA/SDO)
MYTH: Solar flares occur at random.(03 of09)
REALITY: Solar flares follow an 11-year cycle.\n\nPictured: Full-disk images of the sun\'s lower corona during solar cycle 23, as it progressed from solar minimum to maximum conditions and back to minimum (upper right). (credit:SOHO/ESA/NASA)
MYTH: 'Aftershocks' are rare.(04 of09)
REALITY: About one in seven flares is followed by an aftershock -- the flare springs back to life, producing an extra surge of ultraviolet radiation.\n\nPictured: Sunspot 1112, crackling with solar flares, spotted by NASA\'s Solar Dynamics Observatory on October 16, 2010. (credit:NASA/SDO)
MYTH: Solar flares were discovered only recently.(05 of09)
REALITY: Solar flares were first observed in 1859 by English astronomer Richard Carrington.\n\nPictured: Sunspots of September 1, 1859 as sketched by Richard Carrington.\n (credit:Wikimedia: Public Domain)
MYTH: Solar flares are small compared to other explosions in our solar system.(06 of09)
REALITY: Solar flares are among the biggest explosions in our solar system. \"They erupt near sunspots with the force of a hundred million hydrogen bombs,\" Robert Lin of UC Berkeley\'s Space Science Lab said in a written statement.\n\nPictured: Solar and Heliospheric Observatory (SOHO) spacecraft image of a solar flare on October 28, 2003.

MYTH: Solar flares can knock satellites from orbit.(07 of09)
REALITY: When satellites do fall out of orbit, it\'s because Earth\'s gravity is pulling them down.\n\nPictured: Solar Dynamics Observatory (SDO) image of an M7.9 class solar flare on March 13, 2012. (credit:NASA/SDO)
MYTH: Solar flares produce sunspots.(08 of09)
REALITY: It\'s actually the other way around. Magnetic fields associated with sunspots -- cool, dark regions of the sun\'s surface -- can sometimes give rise to solar flares.\n\nPictured: NASA\'s sun-observing TRACE spacecraft image shows a large sunspot group from September 2000.

MYTH: Solar flares and solar prominences are different names for the same phenomenon. (09 of09)
REALITY: Solar flares and prominences are different. A prominence is a loop of plasma traveling along magnetic field lines. Sometimes this loop collapses back into the sun -- or, if the prominence erupts, a solar flare can result.\n\nPictured: A solar prominence on October 19, 2012, captured by NASA\'s Solar Dynamics Observatory (SDO).
