Its story

139 Tauri is a blue supergiant of class B1Ib in the Bull, around 1,600 light-years away from Earth. It belongs to that rare lineage of suns a hundred thousand times more luminous than ours, sentenced to short lives and explosive supernova endings. What we see as a pale spark on the northern horn of Taurus is in fact a colossal beacon whose light has already been travelling for sixteen full centuries.
