Below the photosphere, the physical conditions of the material of the solar. As optical depth is a function of wavelength, it. Above the photosphere the solar atmosphere is transparent, allowing light to escape. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'photosphere.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. The common definition of the photosphere is the layer from which the bulk of the visible photons are emitted. Veronique Greenwood, Discover Magazine, 22 Feb. Often associated with sunspot activity, prominences release. 2021 The outer regions from the photosphere up (the chromosphere and corona) are actually very thin, with pressures generally 1% or less of Earth’s surface atmospheric pressure. Photosphere, visible surface of the Sun, from which is emitted most of the Suns light that reaches Earth directly. Prominences are bright arch-like loops that may erupt from the photosphere into the corona. 2014 Like water boiling in a pot, plasma cells, or granules, carry heat to the sun’s glowing and visible surface, the photosphere. Tom Yulsman, Discover Magazine, 20 Apr. 2021 The image on the right, acquired at the same time, is a kind of magnetic map of the photosphere. 2022 These Texas-size granules cover nearly the entire photosphere. Matt Hrodey, Discover Magazine, The plume created shocks and pulsations that triggered an eruption, peeling off a chunk of the star’s outer shell called the photosphere. a concrete definition within and across all fields in space science. 2013 That material came from the planet itself, which likely passed through the star’s outer photosphere before falling to its demise. There is a strong urgency in the space sciences to make all existing data AI-ready. The dark spots on the surface of the Sun are known as Sunspots this happens because the. Corey S Powell, Discover Magazine, 11 Aug. The phenomenon of Sunspots happens in the Photosphere. Matt Hrodey, Discover Magazine, 15 June 2023 The photosphere appears black at these wavelengths, because that region is not nearly hot enough to shine brightly in extreme ultraviolet. Recent Examples on the Web Despite their great temperatures, dwarf stars can and do harbor water molecules in their own atmospheres – their photospheres. The photosphere is the portion of the atmosphere where we are able to measure with some confidence the magnetic field that pervades the Sun outer layers.
