Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 01/01/2025Until recently, my favorite examples of this were Jimmy Carter and Betty White. President Carter was three months old when Hubble made his announcement. Betty White was about to turn three years old when we realized there are other galaxies. (4/n) 2543
Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 01/01/2025Hubble’s announcement — Other galaxies exist! Our Milky Way is just one of many! — was made on the third day of the 33rd Meeting of the American Astronomical Society, in a paper read by H.N. Russell. The meeting started on the 30th; maybe Hubble chose New Year’s Day for dramatic effect. (5/n) 2485
Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 01/01/2025For astronomers, the result likely wasn’t a sudden revelation. Hubble had been discussing his evidence with colleagues, and word had gotten around. Many scientists were already sure of the result, and had been for years. They just needed irrefutable evidence.

Michael Zingale @michaelzingale.bsky.social · 01/01/2025What does "in a paper read by H. N. Russel" mean here? Bubble wasn't presenting his own work? 010
