[quote]The European Space Agency/NASA Solar and Heliospheric Observatory, or SOHO, captured this image of a gigantic coronal hole hovering over the sun’s north pole on July 18, 2013, at 9:06 a.m. EDT. Coronal holes are dark, low density regions of the sun’s outermost atmosphere, the corona. They contain little solar material, have lower temperatures, and therefore, appear much darker than their surroundings.
Coronal holes are a typical feature on the sun, though they appear at different places and with more frequency at different times of the sun’s activity cycle. The activity cycle is currently [B]ramping up toward what is known as solar maximum, currently predicted for late 2013[/B]. During this portion of the cycle, the number of coronal holes decreases. During solar max, the magnetic fields on the sun reverse and new coronal holes appear near the poles with the opposite magnetic alignment. The coronal holes then increase in size and number, extending further from the poles as the sun moves toward solar minimum again. [B]At such times, coronal holes have appeared that are even larger than this one.[/B][/quote]
Wow, this is so humbling. That thing is utterly, monstrously titanic. I hope the scientists know their stuff and there isn't any reason to be afraid. I personally find it hard to comprehend what is truly going on there.
damn I hope this is nothing seri
Let's just hope the sun doesn't choose to jettison a few tetratonnes of molten iron when it swaps poles.
THE SUNS GOING OUT HOLY FUCKING SHIT!
SOMEONE FIRE A NUKE AT IT!

nuke will go poop like a soapbubble.

um I dunno what soap you're using if the bubbles are goin poop

And it would be totally unobservable, because everything's nothing compared to the size of the Sun. Apart from other bigger suns.
Maybe it's suntanned.
Interesting, it's pretty big.
But there have been occurances of holes almost as big though.
it's like a really big bald spot that blinds everyone who sees it
Fascinating.
We are all going to
DIE
The sun isn't "half dark". It's just this imaging method that filters out the light of the sun and thus shows us just the corona.
That honestly worries me... A lot...
Maybe then the heat would finally end.

Kind of like the dazzling charm of Colin Mochrie, then.

No need actually.

In short, they aren't dangerous.

As above poster said, the sun would look normal if you somehow managed to look at it. However we use all kinds of wavelengths to see the corona.
It still amazes me that our entire existence depends on the mood of a giant ball of nuclear fire. One powerful solar flare in the wrong direction and it could blast our atmosphere away. Or at the least, fuck up all electronics that our modern lives are build around.
