Well this has got to be the coolest Solar Video I have ever seen! Just released by NASA last week, it shows our Sun in action. Pictures taken by Stereo (Solar TErrestrial RElations Observatory) are stitched together to produce the video. Stereo is basically two space based observatories providing stereoscopic measurements to give us a better understanding of Coronal Mass Ejections or CMEs.
The Stereo mission provides us with a better understanding of why CMEs happen and also provide early warnings for any Earthbound CMEs, since they do major damage to satellites, just about anything electrical, have been known to cause blackouts and if there are any Astronauts working out in space they have to take cover.
Warnings are issued to various tech companies to prepare them for the CMEs, my daughter's boyfriend is an IT guy and gets them so he can prepare for it and warn any clients that he feels may be affected by the CME.
CMEs are the "biggest" explosion in our solar system, equivalent to one billion hydrogen bombs and can travel up to two million miles per hour making the trip to Earth in just 2-4 days!
Since we're on the topic of the Sun I thought I would add a couple of pics I took of the sun. below are pictures taken with a Solar Hydrogen Alpha Telescope, it allows only the hydrogen wavelength of the Sun through, allowing us to see the Chromosphere where all the neat stuff happens. Below you can see on both pictures Solar Prominences, shooting into space, the pic right below you can also see a sunspot as well as the Suns "orange peel" look which is created by thousands of Solar Granules , small convection cells 200-2,000 km in diameter, ever changing, have lifespans anywhere from 8 to 20 minutes.
