Phi 1 Orionis
Hot blue starWhat is Phi 1 Orionis
Phi-1 Orionis is a blue B-type star more than a thousand light-years away, set in the head of the Hunter. It belongs to the dynamic Orion OB1 complex, a fertile region of young suns and bright nebulae that gave birth to many of the stars sketching out winter's most recognisable silhouette. Its raw, hot light travelled for a millennium before reaching human eyes.
