||1912: Horace W. Babcock born ... astronomer, son of Harold Babcock. Working together, they were the first to measure the distribution of magnetic fields over the surface of the Sun. Horace invented and built many astronomical instruments, including a ruling engine which produced excellent diffraction gratings, the solar magnetograph, and microphotometers, automatic guiders, and exposure meters for the 100 and 200-inch telescopes. By combining his polarizing analyzer with the spectrograph he discovered magnetic fields in other stars. He developed important models of sunspots and their magnetism, and was the first to propose adaptive optics (1953). Pic: https://aas.org/obituaries/horace-welcome-babcock-1912-2003

  • 1700: Mathematician, astronomer, and criminal investigator Giovanni Domenico Cassini publishes new study of the division of the rings of Saturn which reveals a series of previously unknown crimes against mathematical constants. This study will influence a generation of crime-fighting astronomers, leading to numerous breakthroughs in scientific law enforcement.
