Comet Lights Off Huge Solar Explosion?


A comet falls into the sun, which then ejects a billion tons of mass. Click on the image above to see the movie.

This movie/video is from the Space Weather website, May 12, 2011.

Here, also from, is a two-second video of the same billion-ton coronal mass ejection.

CME stands for "coronal mass ejection." Here's the May 12 write-up from

"A comet goes in; a CME comes out. Coincidence? Probably, yes, the sequence was coincidental. The comet disintegrated as much as a million kilometers above the stellar surface. There's no known way that the wispy, vaporous remains of a relatively lightweight comet could cause a billion-ton cloud of hot plasma to fly away from the sun at 400 km/s (the observed speed of the CME). Moreover, NASA's Solar Dynamics Observatory photographed the eruption that did propel the CME into space. There's no comet in the field of view of this must-see movie."

That speed, 400 km/second, is nearly a million miles per hour. At that speed, the ejected material would take about a hundred hours to reach the earth -- if it were aimed in our direction.

The energy expended in such a billion-ton ejection is roughly equivalent to all the energy that all human beings could use at our present rate in 200 years.
