Its story

48 Ceti is a white A-type star in Cetus, about 233 light-years away from Earth. Its light comes from a very hot photosphere where hydrogen absorbs in wide, sharp lines —the kind that, together with thousands of sister A-type stars, became a spectroscopic reference standard from the late nineteenth century onward. It shines without fanfare over the celestial sea-monster of northern autumn skies.
