WR 104는 8000광년 떨어진 울프-레이에별이다.

WR 104의 자전축지구와 16도 이내에서 일직선을 이루고 있으며,[1] 이로 인해 WR 104가 초신성 폭발을 일으켰을 때 지구에 영향을 미칠 수도 있다. 초신성 폭발 시 자전축에서 제트가 뿜어져 나오기 때문이다. 그러나 후속 연구로 인해 30~40도(최대 45도)로 GRB경로에서 비켜나 있을 가능성이 크며, 따라서 폭발에도 안전할 것으로 여겨지고 있다.[2]

이때 WR 104가 감마선 폭발을 일으킬 수도 있으며, 이것을 정확히 예보하는 것은 현재 수준으로 불가능하다.[1]
