Here’s yet another glorious photo of our home star, captured and processed by New York artist and photographer Alan Friedman on August 24, 2014. Alan took the photo using his 90mm hydrogen-alpha telescope – aka “Little Big Man” – from his backyard in Buffalo, inverted the resulting image and colorized it to create the beautiful image above. Fantastic!
Hydrogen is the most abundant element in our Sun. The “surface” of the Sun and the layer just above it — the photosphere and chromosphere — are regions where atomic hydrogen exists profusely in upper-state form, and it’s these layers that hydrogen alpha photography reveals in the most detail.
In Alan’s image from Aug. 24 several active sunspot regions can be seen, as well as long snaking filaments (which show up bright in this inverted view – in optical light they appear darker against the face of the Sun) and several prominences rising up along the Sun’s limb, one of which along the left side stretching completely off the frame a hundred thousand miles into space!
