Some of the most energetic and fascinating objects in the Universe are exploding stars known as supernova. These colossal outbursts result from the deaths of stars and for a time can outshine the entire galaxy in which they’re found. Observations of distant supernova provided the first evidence that the expansion of the Universe is speeding up with time, rather than slowing down. This wholly unexpected phenomenon is likely due to a repulsive “dark energy” and has become one of the biggest unsolved mysteries in modern science.
