December 30

Edwin Powell Hubble was an American astronomer who was born at the end of the 19th century. After completing his university studies, he was offered a job by George Ellery Hale, who was the founder and director of the Mount Wilson Observatory. On the 30th in 1924, Hubble made the startling discovery that there existed, outside of our own comfy Milky Way, innumerable other galaxies. The formal announcement of his discovery was made on January 1, 1925. What a delightful way to enter the New Year!
