Amazing video of a solar flare…

…here. It was captured by Japan’s Hinode spacecraft in January: “I managed to stay in my seat,” says solar physicist John Davis of the Marshall Space Flight Center, “but just barely.” Davis is NASA’s project scientist for Hinode, Japanese for Sunrise. The spacecraft was launched in Sept. 2006 from the Uchinoura Space Center in Japan …

There’s a storm a-comin’…

…from the sun. The next Solar Maximum is expected to be a doozy, the biggest since we entered a fully electronic age and ringed our world with satellites. It will be… interesting…to see what effect it has on modern technology.

That unhappy fact has made sunscreens, concoctions that keep ultraviolet radiation …

Sunburn

Summer, contrary to recent evidence in this part of the country, is usually considered the time for fun in the sun. But although some sun is nice, too much sun isn’t, because only 60 percent of sunlight is visible, and only 25 percent is heat. The remaining 15 percent falls in an invisible part of …
