![]() ![]() The red rim can be seen when this H-alpha burns at a high temperature during a total solar eclipse. It’s what we see from Earth with our eyes. It is the H-alpha emission which actually gives the chromosphere its reddish colour. The word photosphere means 'light sphere' which is apt because this is the layer that emits the most visible light. The spectrum of chromosphere has emission lines, with H-alpha lines being the strongest of emission lines. The visible photosphere, or sphere of light, is the level of the solar atmosphere from which we get our light and heat, and it is the part that we can see with our eyes. The spicules are long and thin finger-like gaseous spikes which rise through the chromosphere. Lang, in Encyclopedia of Geology, 2005 The Outer Solar Atmosphere. One of the important features of the chromosphere is the presence of spicules on its edges. The temperature of photosphere, for instance, decreases as it moves away from the Sun. The temperature rises as chromosphere moves farther away from the Sun unlike other objects of the solar system. It is actually the transition between corona and the. During the total eclipse, the moon hides the photosphere and makes way for the reddish chromosphere to be seen.Ĭhromosphere’s temperature ranges from 6,000 to 20,000 degree Celsius. Definition: Chromosphere is a reddish and glowing layer of gas above a stars (or Suns) photosphere. Here, it looks like the chromosphere is the visible surface of the sun, with the photosphere just below. The chromosphere, thus, can be only seen during a complete solar eclipse. member of the science definition team for Solar Orbiter (2003). The temperature of the photosphere depends on the mass and age of a star. the stability of magnetic structures anchored in the photosphere such as coronal loops. It is normally not visible because its density is very low and due to the excessive brightness of the photosphere. The visible surface of a star is called the photosphere. It is about 2,000 to 3,000 kilometres deep, which is located immediately above the photosphere and just below the corona. Photosphre : qu'est-ce que c'est Univers dfinition au sommaire Cela vous intressera aussi Zone constituant la surface visible (aux longueurs d'onde optiques) d'une toile, en particulier. Out of the three layers of the Sun’s atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third).ĭescription: As the name suggests, chromosphere literally translates into ‘sphere of light’. ![]() It is actually the transition between corona and the photosphere.
