Humason
Milton La Salle Humason (August 19, 1891 – June 18, 1972) was an American astronomer. He worked with Edwin Hubble to measure the redshift of nebulas in the early 20th century, providing evidence of the expansion of the universe. Biography Milton Humason was born in Dodge Center, Minnesota, Dodge Center, Minnesota. Humason dropped out of school and had no formal education past the age of 14. Because he loved the mountains, and Mount Wilson (California), Mount Wilson in particular, he became a "mule skinner" taking materials and equipment up the mountain while Mount Wilson Observatory was being built. In 1917, after a short stint on a ranch in La Verne, he became a janitor at the observatory. Out of sheer interest, he volunteered to be a night assistant at the observatory. His technical skill and quiet manner made him a favorite on the mountain. Recognizing his talent, in 1919, George Ellery Hale made him a Mt. Wilson staff member. This was unprecedented, as Humason did n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C/1961 R1
Comet Humason, Astronomical naming conventions#Comets, formally designated C/1961 R1 (a.k.a. 1962 VIII and 1961e), was a List of non-periodic comets, non-periodic comet discovered by Milton L. Humason on 1 September 1961. Its perihelion was well beyond the orbit of Mars, at 2.133 Astronomical unit, AU. The outbound orbital period is about 2,516 years. Physical properties It was a "giant" comet, much more active than a normal comet for its distance to the Sun, with an Absolute magnitude#Cometary magnitudes, absolute magnitude of 1.35−3.5, and a comet nucleus, nucleus diameter estimated at . It could have been up to a hundred times brighter than an average new comet. It had an unusually disrupted or "turbulent" appearance. It was also unusual in that the spectrum of its tail showed a strong predominance of the ion carbon monoxide, CO+, a result previously seen unambiguously only in Comet Morehouse, C/1908 R1 (Morehouse).
