Gender: Male Race or Ethnicity: White Sexual orientation: Straight Occupation: Astronomer Nationality: United States Executive summary: Interstellar dust Astronomer V. M. Slipher discovered the rotations of the spiral nebulae in 1913, the first substantial evidence of a perpetually expanding universe, and he was the first astronomer to measure the spirals' radial velocities. He discovered reflection nebulae, and demonstrated the existence of pulverulent matter, now called interstellar dust. He also discovered the presence of methane in Neptune's atmosphere, made spectrographs of the atmospheres of Jupiter, Saturn, and Uranus, and oversaw the "Planet X" project, which culminated in the discovery of Pluto. Chronically shy, he rarely attended astronomers' gatherings, and instead had his papers read by others at such events. His brother, astronomer Earl Carl Slipher, was Mayor of Flagstaff, Arizona from 1918-20.
