For those reading The First Three Minutes with me – there are a number of black-and-white pictures in the book which were originally published in 1977. While impressive for the time, you now carry better cameras in your pocket than were used by the most advanced researchers then.
A possibly interesting and useful mini-project might be to find and collect higher-resolution images of the pictures in the book. They might be the same images as the original, or newer. In particular, color images of the galaxies and various spectra mentioned.
