O.K. ladies and gentlemen, we’ve addressed the topic of solar flares, coronal mass ejections and other aspects of solar weather several times in the past. And we get great comments and questions from you about this, too.
So here’s another post with a good answer to the nagging question; will Earth be destroyed by a killer solar flare? In a word, according to NASA, no.
Yes, we here on terra firma do get banged and zapped from time to time by great bursts of electromagnetic energy and particles from the sun. That can cause disruptions to satellite and other forms of electronic communications, as well as jeopardize segments of our power grid.
In today’s technologically-rich environment, those outbursts from the sun can be a bit more than inconvenient. But, it appears that more and more people seem to be getting worked up over the Earth coming to an abrupt end, courtesy of a catastrophic blast from the sun.
For some, this fear has been heightened by the so-called the “2012 phenomenon.” The Mayan long count calendar finishes its 5,125-year-long cycle on Dec. 21, 2012, and some believe that will result in the destruction of our planet due to any number of terrestrial or extraterrestrial calamities.
Some believe it will be in the form of a gigantic killer solar flare, which would hurl enough of the sun’s energy at us to destroy Earth. Couple the 2012 phenomenon with the fact that solar activity is ramping up in its standard 11-year cycle, and more credence is given to those who believe the sun will be the cause of Earth’s undoing.
But please be assured that this same solar cycle, which peaks with something called the solar maximum, has repeated itself over and over many times throughout the millennia.
If you’re older than 11, you’ve already lived through at least one solar maximum with no harm done. To those worried about its effect on the 2012 phenomenon, the next solar maximum is predicted to occur in late 2013 or early 2014, not 2012.
NASA assures us, most importantly, that there simply isn’t enough energy in the sun to hurl a killer fireball 93 million miles to destroy Earth.
