Abstract

Slipher and Hubble With all the evidence Slipher had assembled, why didn't he put the pieces together to theorize that the universe is expanding? In deference to Slipher's work on radial velocities, Hubble added in his own hand, "I avoid the subject of radial velocities of nebula, leaving the consideration [of] that entirely to you." Hubble outlined his ambitious "general nebular program" for Mount Wilson Observatory in a February 23, 1922, letter to Slipher, who chaired the Nebular Section of the International Astronomical Union (IAU). FEATURES One hundred years ago this autumn, Edwin Hubble spotted a Cepheid variable star in the Andromeda Galaxy (see page 26). [Extracted from the article]
