It’s the job of NASA’s Solar Dynamics Observatory to keep an eye on the sun, a job the SDO has presented in a new video showing off three years’ worth of solar activity.
“In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar Dynamics Observatory has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle,” NASA said in a release.
The observatory captures an image of the sun every 12 seconds and does so on 10 different wave lengths (you can see some of the wavelengths separated out later in the video). The video actually shows the sun at 171 angstroms, which is in the extreme ultraviolet, and out of the normal visual range of human eyes. The wavelength was chosen because it makes it easy to see the turbulent activity on the surface of the sun as well as its 25-day rotation.
“During the course of the video, the sun subtly increases and decreases in apparent size. This is because the distance between the SDO spacecraft and the sun varies over time,” NASA explains.

Nice eye candy here...
It was amazing, but I thought the video editing was amaturish.

Hay, it's the "New NASA", it ain't even close to what it used to be.
Thanks, missed that post. I neglected my FReeping lately because of silly hobbies like work :(
Nah - all that stuff just happens all by itself. /s
Pardon Me While I Burp

A minute ago
I never thought I would be so thirsty
In need of serious carbonation, coke, or pepsi
But I guess that I drank too passionately
Cuz bubbles of gaseous air are rising up
Like it’s an emergency
I shotgunned a bear
I needed to pee
But now it seems that
belching is a definite probability
To me
So pardon me while I burp
Into your face
It’s bad enough, but what’s worse
You’ll smell what I can taste
So pardon me while I burp
Right into your face
Pardon me, Pardon me
My breath could light a flame
Two Sundays ago
I was having a lunch after brunch
When I felt all the food
Crawling back up my throat
I said I should just belch
Cuz lately I’ve had chronic indigestion
And it’s blocking my connection to
The atmosphere of Planet Burp
Like cavities, toxcicities
And the perils of eating Chinese
And stinking so much differently
So pardon me while I burp
Into your face
It’s bad enough, but what’s worse
You’ll smell what I can taste
So pardon me while I burp
Right into your face
Pardon me, Pardon me
Won’t ever smell the same
Won’t ever smell the same, yeah
It is a shame this solar cycle is a relatively weak one. Would have seen some rip roaring UV emissions if it was very active. Amazing that the Ozone Hole Theory and the Global Warming Theory were both based on assuming that solar emissions were not significantly variable. This was primarily based upon observations of total solar irradiance. Variance at all wavelengths was not even accurately known at the time and was just assumed to be the same.
