Churning in space, around which our entire solar system exists, I'm glad you're here!

The recent Mercury transit got me thinking of all of my favorite images of the Sun. I decided to put a few together and WOW! They are stunning!
I recently saw an incredibly detailed picture of a sunspot and I truly couldn't believe the clarity! This image below simply takes my breath away! It is from 2002 and was the APOD for Nov 14th that year. http://apod.nasa.gov/apod/ap021114.html

Speaking of twitter (and Facebook), get to know Camilla Corona (Space Chicken), the mission mascot for NASA's Solar Dynamics Observatory, a super fun sciencey chicken that worked at the NASA Goddard Space Flight Center and is a STEM Ambassador at the Stanford Solar Center! @CamillaSpace is her Twitter handle!
I LOVE this next image from the Stanford Solar center! It has beautifully merged solar images into a quilted sun :-) It was their webpage cover! Clever!

"Explanation: One of the largest sunspot regions in recent years is now crossing the Sun. This region of convoluted magnetic fields may well produce a solar flare that releases a cloud of energetic particles into the Solar System. Were a very powerful cloud to impact the Earth's magnetosphere, it could be dangerous to Earth-orbiting astronauts and satellites. Conversely, the impact of even a less energetic cloud might create picturesque aurora. This is the sunspot region as it appeared two days ago. The rightmost part of this region has been cataloged as AR 11785, while the left part as AR 11787. The darkest sunspot regions contain nearly vertical magnetic fields and are called umbras, while the surrounding bronze regions -- more clearly showing stringy magnetic flux tubes -- are called penumbras. Churning solar granules, many about 1000 km across, compose the yellow background region. No one knows what this sunspot region will do, but space weather researchers are monitoring it closely." ~ APOD

I'm sure I'll post more sunspot fabulosity at some point. Living with a mid-sized whitish decently-healthy star is awesome indeed!
Just for fun.....see below! HAHAHA! :-)
