A sunspot on the far side of the Sun has been discovered to be so large that “it is affecting the way the sun vibrates,” according to Spaceweather.com. The same region also produced a major coronal mass ejection and radiation storm on September 5; luckily for us the eruption isread more
The sun’s solar flare activity appears to be hotting up: a massive X-Class solar flare erupted early on Sunday (Oct. 19) from a huge sunspot, and astronomers fear that this could just be the beginning of a spate of sizeable flares.
Solar flares are explosions of energetic radiation that can have potentially devastating effects on our communication systems, causing radio blackouts and affecting satellite measurements. Flares are categorised into three types, with grade C being the least powerful, grade M a medium-level flare, and grade X being the most powerful of all. NASA’s Solar Dynamics Observatory (SDO) spacecraft captured images of the latest huge flare which was classified as a formidable X1.1.

Researchers have discovered a link between solar flares and radioactive elements on Earth. Amazing as it sounds, the sun, 93 million miles away, seems to be influencing the decay of radioactive elements inside the Earth. David Sereda talks with William Henry about this in the latest Revelations.

Alas, it’s us humans – People are in denial about climate change (and other things as well), but no matter what they say, scientists insist that sunspots and solar cycles are not the cause of current global warming.
The idea that sunspot activity is the cause of global warming just isn’t true. The problem started with studies published in 1991 and 1998 that claimed to establish a link between global temperatures and solar activity. However, most scientists now believe that these studies are seriously flawed. When the errors in them were removed by researcher Peter Laut, the link between sunspots and global warming disappeared as well. While the sun plays a role in climate change, it is a very minor one.
