Browsing: Chromosphere

The chromosphere is a layer of the Sun’s atmosphere located above the photosphere and below the corona. It is approximately 2,000 to 3,000 kilometers thick and is primarily composed of hydrogen gas. The chromosphere is characterized by its reddish color, which is most prominently visible during a solar eclipse, when the bright light of the photosphere is obscured. This layer plays a critical role in the Sun’s overall energy dynamics, as it is the region where the temperature rises dramatically from the cooler photosphere below to the much hotter corona above. The chromosphere is also where solar phenomena such as spicules, prominences, and solar flares originate, contributing to the Sun’s complex magnetic activity and influencing space weather that can impact Earth.
