When a massive star explodes as a supernova, the temperature in its core can spike to an unimaginable 3 billion °C. At this extreme heat, atomic nuclei are torn apart, and new heavy elements—like gold, uranium, and platinum—are forged in seconds. For a brief moment, the dying star becomes hotter than anything else in the universe, unleashing more energy than the Sun will produce in its entire lifetime. This is how the universe recycles stars into the building blocks of planets and life. #Superno
