Crossword clues for chromosphere

Chromosphere \Chro"mo*sphere\, n. [Gr. ? color + E. sphere.] (Astron.) An atmosphere of rare matter, composed principally of incandescent hydrogen gas, surrounding the sun and enveloping the photosphere. Portions of the chromosphere are here and there thrown up into enormous tongues of flame.

n. (context star English) The faint pink extension of a star's atmospheric envelope between the corona and the photosphere
WordNet
n. a gaseous layer of the sun's atmosphere (extending from the photosphere to the corona) that is visible during a total eclipse of the sun
Wikipedia
The chromosphere (literally, "sphere of color") is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilometers deep. The chromosphere's rosy red color is only apparent during eclipses. The Chromosphere sits just above the photosphere and below the solar transition region. The layer of the chromosphere atop the photosphere is homogeneous. A forest of hairy appearing spicules rise from the homogeneous layer some of which extend 10,000 km into the corona above.
The density of the chromosphere is only 10 times that of the photosphere, the layer beneath, and 10 times that of the atmosphere of Earth at sea level. This makes the chromosphere normally invisible and it can be seen only during a total eclipse, where its reddish color is revealed. The color hues are anywhere between pink and red. However, without special equipment, the chromosphere cannot normally be seen due to the overwhelming brightness of the photosphere beneath.
The density of the chromosphere decreases with distance from the center of the Sun. This decreases logarithmically from 10 particles per cubic centimeter, or approximately to under at the outer boundary. The temperature decreases from the inner boundary at about 6,000 K to a minimum of approximately 3,800 K, before increasing to upwards of 35,000 K at the outer boundary with the transition layer of the corona. Figure 1 shows the trends which density and temperature follow through the chromosphere.
Chromospheres have been observed also in stars other than the Sun.
Usage examples of "chromosphere".
On young worlds they bathed in the scarlet splendor of volcanoes, rhymed solemnly to each other and made love in the cold light of moons drawn close to dying mother worlds, dove headlong through the chromospheres of small suns to prolong their high on rarefied gases.
The photosphere was the outermost layer of the sun except for the chromosphere, and was dominated by granular cells.

If it were normally in the sun's chromosphere, or coronal atmosphere, he said, it would combine with the hydrogen which we know is there and form an obscuring envelope of water vapor.

Looking down the vast promontory of his nose he has beheld everything – the Cordilleras falling away into the Pacific, the history of the Diaspora done in vellum, shutters fluting the froufrou of the beach, the piano curving like a conch, corollas giving out diapasons of light, chameleons squirming under the book press, seraglios expiring in oceans of dust, music issuing like fire from the hidden chromosphere of pain, spore and madrepore fructifying the earth, navels vomiting their bright spawn of anguish… He is a bright sage, a dancing seer who, with a sweep of the brush, removes the ugly scaffold to which the body of man is chained by the incontrovertible facts of life.
The pulsing of the photospheric cells send ripples of gravitation upwards through the chromosphere, subtly strumming chords of space-time across millions of kilometers, and charged particles, riding the crests of Alfven waves, sweep outward in a mighty wind.
We were able to pick the Ghosts out from the jumbled light levels in the chromosphere because, no matter how the plane of polarization migrated, we were able to track it and show that the coherency of the light was real and stable with time.
