Pics of the Longest Solar Eclipse of the Century
Vinod writes "Yesterday thousands of people around Asia witnessed the longest solar eclipse of the century. Although it was not clearly visible in some parts due to overcast weather, thousands of people gathered to view this spectacular event. Yesterday's solar eclipse lasted for 6 to 7 minutes, making it the longest solar eclipse of the century. Here is a collection of 33 beautiful images of the solar eclipse from around the world."
I thought eclipses were supposed to cause super powers ... or was it that they took them away? *shakes fist*

these pics look much bigger nicer over at boston.com's The Big Picture, where they were posted yesterday and no doubt scooped and scaled for your link.

---- You are fully entitled to my opinion.
the dude with four pairs of glasses looking at the solar eclipse. Is that even safe? I understand most sunglasses don't even block the dangerous rays and make it even worse to look toward the sun as your eyes are more dilated and the harmful rays burn your eyes even more.
Comments?

I'm guessing that the guy with 3 pairs of sunglasses over his regular glasses must have been a slashdotter. Where else would you find such ingenuity (and such nerdiness)?
Whoever you are, I salute you, my friend.
But then I realized the cable was blue, so I only gave it one star. I hate blue.
Why would we joke? I imagine them to be amazingly effective at protecting your eyes, and rather affordable. After all... they're made of lead!
Even tho it's early in the century, it might well be the longest eclipse of the century. I imagine that the calculations to predict eclipses and their duration would be relatively straightforward by modern standards. You probably wouldn't even need to take relativity into account.
"Welcome to our world. We are the wasted youth. And we are the future too." Yes, I know these are stupid lyrics.
One of the big chemical companies is churning out a mylenised film that makes for an effective pair of eclipse glasses. It's a really bad idea to look directly at the sun during an eclipse because the iris expands in response to the low mean light level and provides little to no protection from the high peak light level when the photosphere is visible. Wearing the mylenised glasses doesn't make your iris expand any wider, but it does cut down that peak light level dramatically.
No kidding!!! What do you say at this point?
Actually, during totality, looking at the sun (or rather, the moon and the solar corona) completely unfiltered is a Not Bad If You Know What You're Doing Idea. But you're supposed to look away as soon as totality ends, and it's easier to recommend nobody looks at all than to try educating people on the difference between total, partial, and annular eclipses, and the different stages of a total eclipse.
And since the introduction of arc welding, suitable thin films have been used in lenses for welding helmets. It's my understanding that these are frequently peddled in disposable holders for viewing solar eclipses.
