Pictured above, in all its glory, is the constellation of Orion's Belt. Alnilam, the star in the middle of the belt, is 1340 light years away. That means if you look up and see it tonight, the light that you'll see left the star 1340 years ago. #tbt 🌟 . . . . . . . . . #science #space #lightyears #light #throwback #throwbackthursday #star #sky #nightsky #Orion #orionsbelt #constellation #stars #stargaze #astronomy #physics
