The sun ejected two huge solar flares Tuesday, and NASA says that we here on Earth may notice the effects of magnetic fields and ionized gases that it estimates will arrive around 1:25 a.m. ET Thursday. So, if you detect some electronic interference — say, your GPS doesn't work right — blame it on the sun.
In NASA's video of the mass ejections of solar matter, they look powerful, even angry — like massive solar blisters. As NASA says, "One of the most dramatic features is the way the entire surface of the sun seems to ripple with the force of the eruption."
