Sunspots, Which Can Harm Electronics On Earth, Are Half The Number Expected




” Scientists say that solar activity is stranger than in a century or more, with the sun producing barely half the number of sunspots as expected and its magnetic poles oddly out of sync.

The sun generates immense magnetic fields as it spins. Sunspots—often broader in diameter than Earth—mark areas of intense magnetic force that brew disruptive solar storms. These storms may abruptly lash their charged particles across millions of miles of space toward Earth, where they can short-circuit satellites, smother cellular signals or damage electrical systems.

Based on historical records, astronomers say the sun this fall ought to be nearing the explosive climax of its approximate 11-year cycle of activity—the so-called solar maximum. But this peak is “a total punk,” said Jonathan Cirtain, who works at the National Aeronautics and Space Administration as project scientist for the Japanese satellite Hinode, which maps solar magnetic fields.”


Are the lights about to go out ? End times anyone ?











” Filmmaker Joey Shanks describes it as “magic” or a “strange material.” A commenter said it’s “like a constrictor consuming a rat.” What is it? Magnetic putty.

The putty, like the type dubbed Super Magnetic Thinking Putty® from Putty World, is designed to “attract one magnetic pole and repel from the other.”

Shanks, in coordination with PBS Digital Studio, showed off the mesmerizing properties of the material in a recent video.”
