词条色球

描述: 太阳或其他类太阳恒星的色球是其大气层中直接位于光球之上的薄层，光球就是发出阳光或星光的密度较大的一层。在日全食期间，可观测到一圈微弱的发光气体环，其成分主要是氢气，会发出红色的光，色球因此得名。

The Sun as red disk with bright patches and long dark strands. Several small wispy features protrude from the disk's edge

H-alpha image of the Sun's chromosphere

图注： This false-color image was captured with a 10-cm telescope at the Big Bear Solar Observatory (BBSO) in the United States in July 2002. It depicts the full disk of the Sun using the H-alpha emission line of hydrogen. When observed in this spectral line, the Sun's chromosphere appears particularly prominent due to hydrogen atoms emitting light at the specific wavelength. This emission produces a distinctive red color, making features such as spicules (jets of plasma that look hair-like) and plage (bright patches in the chromosphere) highly visible. Several small solar prominences can be seen protruding from the edge of the solar disk. When prominences (also known as filaments) cross the face of the disk they appear as dark threads caused by the cooler material in the prominence absorbing light. The chromosphere is also visible in the violet part of the solar spectrum due to ionized calcium showing emissions in these wavelengths.
