A Branching “Tree” of Solar Plasma

Article Updated: 23 Dec , 2015


Hydrogen-alpha photo of the Sun by Alan Friedman

An enormous tree-shaped prominence spreads its “branches” tens of thousands of miles above the Sun’s photosphere in this image, a section of a photo acquired in hydrogen alpha (Ha) by Alan Friedman last week from his backyard in Buffalo, NY.

Writes Alan on his blog, “gotta love a sunny day in November!”

Check out the full image — along with an idea of just how big this “tree” is — after the jump:

Taken through a special solar telescope and a Grasshopper CCD camera, Alan’s gorgeous solar photos show the Sun in a wavelength absorbed by atomic hydrogen — most present in the photosphere and chromosphere — thus revealing the complex and dynamic activity of the Sun’s “surface”.

Here’s the full image:

The dark circle at upper left (added by me) shows approximately the scale size of Earth (12,756 km, or about 7,926 miles diameter.) As you can see, that particular prominence is easily six times that in altitude, and spreads out many more times wider… and this isn’t even a particularly large prominence! As far as solar activity goes, this is a non-event. (Not like what was seen by SDO on Nov. 16!)

Regardless, it makes for an impressive backyard photo.

Check out more of Alan’s photos on his blog and on his website, Many of his photos, some of which have been shown at galleries across the U.S., are available as limited-edition prints. (Alan also runs a greeting card print studio.) I’ve found that he usually shares at least a couple of fantastic solar shots every month, if not more.

Reminds me of scans of sperm attacking an ova.

There’s one in every crowd. Lil I was thinking it either looks like a ball of frozen OJ with pulp, or an extreme close up of a Nerd ball.

This stuff is fashinating

New and old Science A new and Progressive Science shows how Wavevolution, or the transformation from waves to atoms, is the connecting link that closes the circle of science to open our eyes toward new horizons never seen before. The bureaucracy of traditional science prevents the recognition of any event unless certain criteria are first met. The problem of this science is buried deep in the compilation of these “laws” or criteria introduced by a few scientists in the name of all science and from their erroneous understanding of the relation between Space and Time. This antiquated system of rules also results in misleading theories. For example, Space is not “curved”. In Einstein’s paradigm, a stone that falls… Read more »

Ahem…You have chosen the wrong forum for your comment! Youthful exuberance… or egotistic hubris? I see from your bio that you are also VERY politically and religiously opinionated…. Although one may or may not agree with your point of view, your method of repetitious delivery obfuscates your intent. Are you entirely oblivious of that? HI! “jtStar”…. dzzzzz
