  • Photosphere - Wikipedia
    The photosphere is a star's outer shell from which light is radiated It extends into a star's surface until the plasma becomes opaque, equivalent to an optical depth of approximately 2⁄3, [1] or equivalently, a depth from which 50% of light will escape without being scattered
  • Photosphere | Sun’s Surface, Solar Radiation Solar Flares | Britannica
    photosphere, visible surface of the Sun, from which is emitted most of the Sun’s light that reaches Earth directly
  • The suns atmosphere: Photosphere, chromosphere and corona
    The term photosphere means "sphere of light" and is the layer where most of the sun's energy is emitted It takes about eight minutes for sunlight from the photosphere to reach Earth
  • Photosphere - NSO - National Solar Observatory
    What we are actually seeing is a thin layer surrounding the Sun This part of the Sun is very thin (just 100 km or 62 miles thick) compared to other regions of the Sun, such as the corona and chromosphere Within this zone, we see sunspots, solar flares, granules and convection cells
  • The Surface of the Sun - Center for Science Education
    The surface of the Sun is called the photosphere, a term which means “sphere of light ” The glowing ball of light that you see in the sky is the photosphere
  • The Solar Photosphere - Stanford University

  • Photosphere - an overview | ScienceDirect Topics
    The photosphere is defined as the deepest and coolest layer of the solar atmosphere, with temperatures ranging from approximately 6000–7000 K at an optical depth of unity (τ 500 = 1) and an extension of about 500 km
  • Photosphere - solar. physics. montana. edu
    We term the region where this happens the apparent surface, or the photosphere The photosphere is the disk you see in the sky when you look at the Sun through a filtered telescope or as a projection on a piece of paper
  • Solar photosphere | Research Starters - EBSCO
    The photosphere plays a crucial role in the Sun's luminosity, affecting solar radiation that reaches Earth and potentially influencing climate change Observing this layer has revealed significant insights into solar cycles and the relationship between solar activity and historical climate events
