18 de abr. de 2024 · Vesto Melvin Slipher - 1912 While observing spiral galaxies, found that they all seemed to be redshifted by some amount! This would imply that they are all moving away from us, which seemed somewhat odd; Edwin Hubble - 1929 Used Type Ia supernova to estimate the distances to distant galaxies; Found that the more distant galaxies were ...
28 de abr. de 2024 · April 28, 2024, 3:45 PM. Starting in 1912 the American astronomer Vesto Slipher discovered that the spectra of “spiral nebulae” (now called galaxies) displayed large redshifts. This was different from the spectra of stars, which showed an even mix of red and blue shifts.
Hace 1 día · Vesto Melvin Slipher, the observatory director, gave the job of locating Planet X to 23-year-old Clyde Tombaugh, who had just arrived at the observatory after Slipher had been impressed by a sample of his astronomical drawings.
24 de abr. de 2024 · However, although Hubble did indeed experimentally demonstrate the linear relation between the spectral redshift of galaxies and their distance from us, he neither discovered such systematic spectral shifts (the discovery goes back to the American Vesto Slipher), nor did he accept the relativistic interpretation of his observations ...

Hace 3 días · Vesto Slipher was an American astronomer who first calculated the speeds of galaxies. He calculated the distance by looking at the light spectrum, and the redder it is, the object is moving away with blue, meaning it's coming near you. National Geographic.
Hace 5 días · Slipher już w AD 1914 przedstawił pierwsze wyniki takich pomiarów, ale nikt, w tym także sam Slipher, nie potrafił wówczas zinterpretować takiego efektu. ( Vesto Melvin Slipher – 1875 – 1969, astronom amerykański, pracował w Lovell Observatory.
