A Big Solar Burp Pelted Earth Last Night

THE SUN IS throwing a fit. For the second time this week it has launched massive chunks of itself at us—from 93 million miles away.

Don’t be offended: This is all part of the normal solar weather cycle. Every so often, turbulence on the sun’s surface erupts, shooting radiation and ionized particles earth-ward. When it’s bad, it can fry satellites, and take them offline, disrupt the electrical power grid and expose astronauts and airline passengers to harmful radiation.

The solar storm that reached us yesterday turned out smaller than expected, causing no-known damage. But, if you were lucky, it did treat you to celestial nighttime light show.

Solar storms are what create the aurora borealis—the ethereal colored lights sometimes seen dancing in the night sky, especially at high altitudes.

But catching auroras from solar storms remains largely a matter of luck. Despite almost 200 years of working on solar storm predictions, scientists still have but a few hour’s warning that a storm’s a brewin’. And they have just a few minute’s warning about how intense it will be. So often people who spy the auroras have no idea they’re coming until they’ve arrived.

2. Thanks! I thought it was spectacular, too

Photos like this help put things in perspective, how small we are in the universe. And I thought it was cool that the photographer was Scott Kelly, twin brother of Mark Kelly, Gabby Giffords' husband.

4. Wow! You're right! Guess they really got the special effects!

I know I saw this, but it was an awfully long time ago, LOL. I had forgotten the Klingons could be like that...

And there's the fabulous George Takei! It would be worthwhile to see these films again, just to see him!
