![]() ![]() The cloud-like character which he attributed to the radiant shell of the sun (first named by Schröter the " photosphere") is borne out by all recent investigations he observed its mottled or corrugated aspect, resembling, as he described it, the roughness on the rind of an orange showed that "faculæ" are elevations or heaped-up ridges of the disturbed photospheric matter and threw out the idea that spots may ensue from an excess of the ordinary luminous emissions. The surface of the Sun, known as the photosphere, reaches temperatures of 5,000 degrees. 382 variability, 382 photon noise, 87 photosphere definition, 1 physical constants Appendix A, 488 pressure electron, definition, 13 gas, definition. noun 0 0 The lowest visible layer of a star, lying beneath the chromosphere and the corona. The term itself is derived from Ancient Greek roots,, /phos, photos meaning 'light' and /sphaira meaning 'sphere', in reference to the fact that it is a spherical surface that is perceived to emit light. What we observe is the surface-layer, the so-called photosphere, in which the cold of space produces the condensation of the gases into those luminous clouds which we see in our drawings and photographs as "rice grains" or "willow leaves." Photosphere definition ft-sfr Meanings Synonyms Sentences The directly visible outer layer or atmosphere of a star, especially of the sun. The photosphere of an astronomical object is the depth of a star's outer shell from which light is radiated. Up, Up and Away! Helium Balloon Telescope Explores the Sun | Universe TodayĪn elastic fluid, now known as the photosphere, is in course of continual formation on the dark rugged surface of the solar mass and rising, on account of its specific lightness, it forms the pores in the stratum of reflecting clouds then, combining with other gases, it produces the irregularities or furrows in the luminous cloud-region. This paper suggests that plasma motion in an active region in the photosphere is the source of large electric currents. ![]() The photosphere is the surface that emits solar radiation to space. SciFi, Fantasy & Horror Collectibles - Part 1067 The surface layer of the Sun that we can see is called the photosphere and has a temperature of about 5800 degrees Kelvin. But compressed gas in the thicker, denser part of the Sun mashes together all those energies, spreading them out, so it emits white light (that layer of the Sun is called the photosphere).ĭetailed Pictures Of The Sun Let You Get Up Close And Personal With The Star (PHOTOS) ![]()
