Sama ita ce duban sama mara tsangwama daga saman ƙasa. Tana ƙunshe da yanayi da kuma tashar sararin samaniya. Ana iya ɗaukar ta a matsayin wuri tsakanin ƙasa da sararin samaniya, don haka ta bambanta da sararin samaniya.

A fagen astronomy, ana kuma kiran sama da celestial sphere. Wannan ƙwallon ƙirari ce mai faɗi, ciki ga duniya, inda Rana, Wata, Duniya da kuma taurari suke bayyane kamar suna motsi. Ana raba fuskar taurari ta fuskar ƙirari zuwa wurare da aka ƙayyade da ake kira constellations.

Yawanci, kalmar sama tana nufin fassarorin daga saman ƙasa; duk da haka, ma'anar da amfani zasu iya bambanta. Wanda yake kan saman ƙasa zai iya ganin ƙaramin ɓangare na sama, wanda yake kama da gindin kwano (wani lokaci ana kiran shi kwano na sama) yana bayyana flat lokacin rana fiye da dare.^[1] A wasu lokuta, kamar a lokacin da ake tattauna yanayi, ana nufin ƙananan, mafi yawan matakan yanayi kawai.
