Shock wave around supernova 1987A (captured by the Hubble Space Telescope), This image shows the entire region around supernova 1987A. The most prominent feature in the image is a ring with dozens of bright spots. A shock wave of material unleashed by the stellar blast is slamming into regions along the ring's inner regions, heating them up, and causing them to glow. The ring, about a light-year across, was probably shed by the star about 20,000 years before it exploded.

超新星1987A周辺の衝撃波。画像の最も顕著な特徴は、数十個の明るい斑点を持つリングである。恒星の爆風によって発生した衝撃波が、リングの内側の領域に激突し、それを加熱して光を放つ。直径約1光年のリングは、おそらく爆発するまで約2万年前に星に取り除かれていた。
