• ... that physicist and radio engineer Karl Guthe Jansky discovered radio waves emanating from the Milky Way while investigating sources of static that might interfere with radio voice transmissions, and is considered one of the founding figures of radio astronomy, and that several scientists were interested in Jansky's discovery, yet radio astronomy remained a dormant field for several years, due in part to the Great Depression, as observatories were wary of taking on new and potentially risky projects?
• ... that Pale Blue Dot is a photograph of planet Earth taken on February 14, 1990, by the Voyager 1 space probe as part of the Family Portrait series of images of the Solar System, and that Voyager 1, which had completed its primary mission and was leaving the Solar System, was commanded by NASA to turn its camera around and take one last photograph of Earth across a great expanse of space at the request of astronomer and author Carl Sagan?
• ... that a routine annual steganographic checkup of Alice and Niles Dancing in 2017 unexpectedly revealed "at least two hundred and fifty-six, possibly five hundred and twelve" love letters between mathematicians and alleged time-travellers Alice Beta and Niles Cartouchian?
• ... that physicist Owen Willans Richardson won the Nobel Prize in Physics in 1928 for his work on thermionic emission, which led to Richardson's law, and that Richardson also researched the photoelectric effect, the gyromagnetic effect, the emission of electrons by chemical reactions, soft X-rays, and the spectrum of hydrogen?
