    • About the Photosphere
      • When you look at the Sun with a filtered telescope you can see evidence in the photosphere of the convective bubbles in the convection zone below. The continuous rising and falling of hot and cool bubbles produces a pattern on the surface of the Sun that is referred to as granulation.

  1. Aug 11, 2014 · A number of features can be observed in the photosphere with a simple telescope (along with a good filter to reduce the intensity of sunlight to safely observable levels). These features include the dark sunspots , the bright faculae , and granules .

  3. 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. You should never look at the Sun directly, it can cause blindness.

  4. Photosphere, visible surface of the Sun, from which is emitted most of the Sun’s light that reaches Earth directly. Since the Sun is so far away, the edge of the photosphere appears sharp to the naked eye, but in reality the Sun has no surface, since it is too hot for matter to exist in anything.

  5. Feb 3, 2024 · Photosphere. Thickness/Size: Approximately 500 kilometers. Temperature: Around 5,500°C. Characteristics: The photosphere is the Sun’s visible surface, where light is emitted that we see from Earth. It’s marked by granules and sunspots, which are manifestations of the Sun’s magnetic activity.

  6. Similar to the patterns you can see at the top of a pot of boiling water, granulation is caused by heat rising to the photosphere from the hotter solar interior. Where the hot, rising blobs of plasma reach the surface, we see bright areas.

  8. The photosphere is the lowest layer of the solar atmosphere. It is essentially the solar "surface" that we see when we look at the Sun in "white" (i.e. regular, or visible) light. When we observe sunspots and faculae (bright little cloud-like features) we are observing them in the photosphere.
