Astronomers have cracked a decades-old cosmic mystery: two stars in our Milky Way exploded as supernovas — one famous, one hidden — and they’re siblings. The second, called G189.6+3.3, was nearly invisible until scientists combined Fermi telescope data with new X-ray scans, spotting a gamma-ray glow that matched its shell. Simulations show the first explosion flung the second star away, letting its blast unfold separately — a rare, cosmic double act that gives us a new window into how stellar energy spreads and shapes galaxies. Now, researchers are hunting for more of these twin supernovas to…
