Vesto Melvin Slipher ( Mulberry, Indiana, 11 de noviembre de 1875- Flagstaff, Arizona, 8 de noviembre de 1969) fue un astrónomo estadounidense. Entre sus investigaciones destacan haber medido por primera la velocidad radial de una galaxia y haber descubierto la existencia de gas y polvo en el medio interestelar.
Vesto Melvin Slipher ( / ˈslaɪfər /; November 11, 1875 – November 8, 1969) was an American astronomer who performed the first measurements of radial velocities for galaxies. He was the first to discover that distant galaxies are redshifted, thus providing the first empirical basis for the expansion of the universe.
Vesto Melvin Slipher. (Mulberry, 1875 - Flagstaff, 1969) Astrónomo estadounidense cuyas observaciones cósmicas proporcionaron los primeros datos empíricos en los que se sustentó la teoría del universo en expansión. Hijo de un granjero, realizó estudios de física en la Universidad de su estado natal. Se graduó en 1901 y comenzó a ...
9 de abr. de 2024 · Vesto Slipher was an American astronomer whose systematic observations (1912–25) of the extraordinary radial velocities of spiral galaxies provided the first evidence supporting the expanding-universe theory.
Vesto Melvin Slipher (1875 - 1969) History. This page is motivated by a feeling I have held for some years: that a very large share of the credit for the discovery of the expanding universe is due to Slipher, and yet he tends to take very much second place to Hubble in most accounts.
Slipher discovered and measured the rotations of the spirals. He also made extensive studies of the spectra of the night sky and the aurorae. As director he organized and supervised the successful search for a ninth planet .
VESTO MELVIN SLIPHER, a pioneer in the field of astro- nomical spectroscopy during his long career at the Lowell Observatory at Flagstaff, Arizona, probably made more fundamental discoveries than any other observational astronomer of the twentieth century.1 He is best known for his discovery in 1913 of the extraor-dinary radial velocities of the...
