Which newspaper reported Hubble's galaxy findings on November 23, 1924?

The story behind the answer

The New York Times reported Hubble’s galaxy findings on November 23, 1924.

The report described Hubble’s evidence that spiral nebulae were actually stellar systems outside the Milky Way. At the time, astronomers were still debating whether the Milky Way contained the entire universe or whether the spiral nebulae were separate “island universes.” Hubble’s observations of Cepheid variable stars in Andromeda provided a way to estimate its distance and showed that it lay far beyond the accepted boundaries of the Milky Way.

The newspaper story appeared before the formal scientific presentation of the work. This helped bring the discovery to public attention while astronomers were still assessing its implications. Hubble’s formal paper was subsequently presented at a meeting of the American Astronomical Society on January 1, 1925.

Readers sometimes confuse the newspaper date with the publication date of Hubble’s technical paper, which appeared later in December 1924. They refer to related stages of the same episode, but the newspaper that reported the discovery on November 23 was The New York Times.
