The document discusses the Galaxy Forum event being held at Scarsdale High School on September 30th. It provides background on galaxies, noting they were first postulated by Galileo in 1610 and later observations by Hubble and Lemaître confirmed the expansion of the universe. It notes there are an estimated 100-400 billion stars in the Milky Way galaxy and the farthest confirmed galaxy is 13.4 billion light years away. The forum will discuss why the Milky Way galaxy should be a focus in the 21st century and the goal of galaxy education for all classes.
