Glossary term: Photosphère
Description: La photosphère ("sphère de lumière") est la couche d'une étoile d'où émerge la lumière que nous observons. La lumière émise par les couches plus profondes et plus denses sera absorbée avant de pouvoir s'échapper de l'étoile. Les couches supérieures sont moins denses et n'émettent pas de lumière significative.
