The Supernova Sonata takes scientific data and turns it into music, with each note representing a Type Ia supernova, with pitch indicating the time it took to peak and fade, and volume the distance to the star. Type Ia supernovae are used to measure distances to galaxies, as features of their light curve tell us their intrinsic brightness, and were essential to the discovery of dark energy http://en.wikipedia.org/wiki/Dark_energy.
Worlds: The Kepler Planet Candidates shows what all the potential candidates discovered by the Kepler Space Telescope at the time would look like if they orbited one star. Some of these have since been found to be false positives, while new candidates have been detected since. However, it gives a sense of the fact that at any moment there are likely to be several candidates transiting in front of stars.
