Lam

Variable star

Its story

Lambda Eridani flows at more than eight hundred light-years, a blue B-type star within the longest river in the sky —that celestial course winding from Orion down to the southern horizon. It is a Be variable: spinning so fast that hot material escapes its equator and forms a luminous disk around it. A current of light within an imagined river.
