This is a movie of an event captured last February that scientists are calling a &#8220;solar tsunami.&#8221; It is a towering wave of plasma that lifts itself more than the width of the Earth above the solar surface and hurls massive amounts of solar matter into space.<\/p>\n<p>From <a href=\"http:\/\/science.nasa.gov\/headlines\/y2009\/24nov_solartsunami.htm\">NASA<\/a>:<\/p>\n<blockquote><p>The twin STEREO spacecraft confirmed their reality in February 2009 when sunspot 11012 unexpectedly erupted. The blast hurled a billion-ton cloud of gas (a &#8220;CME&#8221;) into space and sent a tsunami racing along the sun&#8217;s surface. STEREO recorded the wave from two positions separated by 90o, giving researchers an unprecedented view of the event:<\/p>\n<div align='center'><a href='http:\/\/capnbob.us\/graphics\/imageview.php?image=http:\/\/capnbob.us\/blog\/wp-content\/uploads\/2009\/11\/tsunami.gif' title='tsunami.gif'><img src='http:\/\/capnbob.us\/blog\/wp-content\/uploads\/2009\/11\/tsunami.thumbnail.gif' alt='tsunami.gif' \/><\/a><\/div>\n<p>Above: A solar tsunami seen by the STEREO spacecraft from orthogonal points of view.
