A bright, star-filled image showing the spiral galaxy NGC 7331, tilted slightly and glowing with soft blue light. Near its dusty lanes and spiral arms, a bright white dot marks the supernova 2025rbs. The foreground is dotted with faint stars from our own Milky Way.

A star exploded 50 million years ago. We just saw it. 💥
Supernova 2025rbs, a Type Ia in galaxy NGC 7331, was detected on July 14 and is now the brightest supernova in Earth's sky. It likely came from a white dwarf’s thermonuclear blast.
