I believe the answer is:
galactic
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">of the milky way</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for galactic that I've seen before include "To do with large independent systems of stars" , "Relating to large star systems" , "More than stellar" , "Of independent system of stars in space" , "Referring to the star system" .)
