Sun's chromosphere. This is one of the first images taken by the Solar Orbiter spacecraft, which launched in February 2020. It was taken at a distance of only 77 million kilometres, the closest that images of the Sun have ever been taken. The chromosphere is a section of the Sun's lower atmosphere. Here it is imaged at a particular ultraviolet wavelength, known as the Lyman-alpha wavelength, that is produced by hydrogen. In the chromosphere electrically charged gas, known as plasma, is increasingly affected by the Sun's magnetic field. Imaged by the High Resolution Imager (HRILYA), part of the Extreme Ultraviolet Imager (EUI) on ESA's Solar Orbiter spacecraft. | |
