Edward Charles Pickering (July 19, 1846 – February 3, 1919) was an American astronomer and physicist [1] and the older brother of William Henry Pickering. Along with Carl Vogel, Pickering discovered the first spectroscopic binary stars. He wrote Elements of Physical Manipulations (2 vol., 1873–76). [2]
William Henry Pickering (February 15, 1858 – January 16, 1938) was an American astronomer. [1] Pickering constructed and established several observatories or astronomical observation stations, notably including Percival Lowell 's Flagstaff Observatory .
Pickering published her work with his name as co-author. The legacy she left allowed future scientists to make further discoveries in space. Astronomer Edwin Hubble used Leavitt's method to calculate the distance of the nearest galaxy to the earth, the Andromeda Galaxy.
Most notably, in 1888, Fleming discovered the Horsehead Nebula on a telescope-photogrammetry plate made by astronomer W. H. Pickering, brother of E.C. Pickering. She described the bright nebula (later known as IC 434) as having "a semicircular indentation 5 minutes in diameter 30 minutes south of Zeta Orionis". Subsequent professional ...
Henrietta Swan Leavitt (/ ˈ l ɛ v ɪ t /; July 4, 1868 – December 12, 1921 [2]) was an American astronomer. [1] Her discovery of how to effectively measure vast distances to remote galaxies led to a shift in the scale and understanding of the scale and the nature of the universe. [3]
William Hayward Pickering is not to be confused with William Henry Pickering, an astronomer from an earlier era. At the time of his retirement as director, in 1976, the Voyager missions were about to launch on tours of the outer planets and Viking 1 was on its way to land on Mars.
No other astronomer ever confirmed Pickering's claim. Pickering attempted to compute an orbit, which showed a fairly high inclination (39.1° to the ecliptic), fairly large eccentricity (0.23) and a semi-major axis (1,457,000 kilometres (905,000 mi)) slightly less than that of Hyperion. The period was supposedly 20.85 days, with prograde motion.
