• Resumen

  • Here, Aron shares his urban supernova-spotting at London's hidden observatory. Nestled among community gardens in a sleepy north London suburb, there is a place where you can watch stars explode. The University of London Observatory (ULO) in Mill Hill is only a few miles down the road from his childhood home. The bright lights of London were a minor concern when ULO opened in 1929, but the city's urban sprawl has since engulfed the telescope domes, and spotting supernovas and exoplanets there can be a challenge. The final stop on his tour is a telescope equipped with a spectrograph, an instrument that splits light into its constituent wavelengths. Each cosmic object emits its own spectrum, revealing clues to its chemical make-up.
