My undergraduate thesis was in making random bits from astronomical sources. Here are some of the data products of that project. Here are the 12 quasars--active galactic nuclei surrounding supermassive black holes devouring stars--which from their lofty perch in the cosmos kindly provided us with some random bits for testing the foundations of quantum mechanics. If you use this data, for fun or for something more serious, we'd be happy if you cited our work!
