3 Tiny Little Flares: Even Tiny Solar Flares on the Sun are Huge

To put this in perspective, “TINY” = 10-20 Earths On May 8, 2010, the sun produced several relatively small solar flares, C and B-class solar flares on the solar flare scale (much like the earthquake Richter scale). In particular, the […]
