APOD: 2009 November 4 - Blue Sun Bristling
Explanation: Our Sun may look like all soft and fluffy, but it’s not. Our Sun is an extremely large ball of bubbling hot gas, mostly hydrogen gas. The above picture of our Sun was taken last month in a specific red color of light emitted by hydrogen gas called Hydrogen-alpha and then color inverted to appear blue. In this light, details of the Sun’s chromosphere are particularly visible, highlighting numerous thin tubes of magnetically-confined hot gas known as spicules rising from the Sun like bristles from a shag carpet. Our Sun glows because it is hot, but it is not on fire. Fire is the rapid acquisition of oxygen, and there is very little oxygen on the Sun. The energy source of our Sun is the nuclear fusion of hydrogen into helium deep within its core. No sunspots or large active regions were visible on the Sun this day, although some solar prominences are visible around the edges.
Sondre Lerche - Dan in Real Life - To Be Surprised

I’m not going to say that you ever stop to think along the way
But baby, be prepared to be surprised. You better be prepared to be surprised.
Baby, be prepared to be surprised It’s all I know
I’m not going to state obvious observations everybody makes
But baby, be prepared to be surprised. You better be prepared to be surprised
Baby, be prepared to be surprised It’s all I know
The weight of the world and the hurt and the dirt
Can make you disturbed but I heard, but I heard
When I wrap my arms around you every mistake we made crumbles
When I wrap my arms around you everything echoes a new song
I’m not gonna whine or scream out I’m so tired through the mike
But baby, be prepared to be surprised. You got to be prepared to be surprised
Baby, be prepared to be surprised It’s all I know
The weight of the world and the hurt and the dirt
Can make you disturbed but I heard, but I heard
When I wrap my arms around you every mistake we made crumbles
When I wrap my arms around you everything echoes a new song
I’m not gonna lie saying everyone’s gonna be alright and fine until we die
But what else can you do but hope and pray and save
And we’ll get by
Be prepared to be surprised
Better be prepared to be surprised
You got to be prepared to be surprised
It’s all I know
Located deep in the Luray Caverns in Virginia’s Shenandoah Valley is the Great Stalacpipe Organ, the worlds largest musical instrument.
Stalactites covering 3 1/2 acres of the surrounding caverns produce tones of symphonic quality when electronically tapped by rubber-tipped mallets.
This most unique, one-of-a-kind instrument was invented in 1954 by Mr. LeIand W. Sprinkle of Springfield, Virginia, a mathematician and electronic scientist at the Pentagon.
