Turns out, supernovas aren’t just epic explosions—they might be the universe’s most powerful particle colliders! But here’s the twist: they only reach their full cosmic-ray-slinging potential if they’ve already blown off a ton of gas (literally, like two suns’ worth) before going boom. When that leftover gas is close by, the supernova shockwave slams into it, cranking up the energy to insane levels—way beyond what our biggest colliders can do. No wonder we haven’t caught one in action yet; the window is super short! #SpaceNews #Supernova #CosmicRays #Science
