When stars run out of gas, they explode in an event termed a supernova. These stellar swan songs are brilliant occurrences, but they quickly fade into oblivion--typically in just a few months time. Astronomers using the European Space Agency's XMM-Newton space observatory have discovered a shining exception this rule, however. Though it has dimmed significantly in visible light, the supernova SN 1979C burns as brightly today in x-ray light as it did at its inception in 1979. Its radiance is allowing experts to glimpse star explosion in unprecedented detail.
