HUDF ir 1/4 area in low center astroHUDFIR2004-07-b-full_tifb 800X800 pixels 1.02 MB pngThe colors have been adjusted to reveal a few faint distant red sources, as well as a background of tiny blue sources, 1-2 pixel size, which are always on the background of dark tangled Murray mesh. Click on All Sizes to view the Original.This view is 93 arc-sec. wide.static.flickr.com/52/121113051_12b5e3b85c_o.pngThe number of the myriad minute blue sources varies noticeably, for instance,from higher south of the bright foreground star, to lower towards the lower right corner. This indicates that simple surveys can collect much detailed information.The value of this simple approach is evident, if we take the tiny blue sources to bethe earliest massive hypernovae and GRBs, markers that highlight the 3D fractilenetwork distribution of mostly H gas filaments, condensing by gravitationalattraction, as the universe bubble continued its expansion. It became coolenough at 380,000 years to allow atoms to form within the former ionized plasma.Transparency emerged from opacity. The intense ultraviolet radiation at 3,000 deg K was redshifted and cooled with the thousand-fold expansion of space-time tocomprise our era's Cosmic Microwave Background at just 2.7 deg K, ubiquitious,and uniform to a few parts in a hundred thousand.See for yourself, Observer, the deep tapestry of our astrophysical history,hung hugely against the uniform red background (downshifted cosmic ultraviolet),the wooly open knit of cooled and condensed H filaments(darkly silhouetting the background),lit like Christmas trees with generations of tiny blue sources,(the downshifted ultraviolet of immense fast-burning, short-lived hypernovae,and a few GRBs, while some twin sources may be the two jet lobes of active galaxies),with vistas of closer and cooler souces,ranging from red, orange, yellow, green, blue, and white,from clump cluster galaxies to irregular, spiral, and elliptical galaxies,and the little kid in our own neighborhood,the red foreground star with its diffraction spikes from the Hubble Space Telescope.I used an excellent low cost image processing program, MGI PhotoSuite 4.0, to adjust the colors to bring out the subtle background details:Touchup feature:Soften: set at 3 of 12 levels, to slightly smooth out the pixels.Color Adjustment: Cyan-Red +75, Magenta-Green -100, Yellow-Blue +50,as empirically this created a pleasing, easy to view image with maximum detail.Brightness: increased from 0 to 20, to increase the dark background details.Gamma: unchanged at 1.00. The pixels are .03 arc-second each, so that the original Hubble Ultra Deep Field, 6200 X 6200 pixels, is 186 X 186 arc-seconds, 3.1 X 3.1 arc-minutes, a tenth of the diameter of the Full Moon or the Sun, 0.5 degrees, 30 arc-minutes. |
