His ashes were interred in a crypt at the base of the 31-inch Keeler Memorial telescope at the Allegheny Observatory. Along with George Hale, Keeler founded and edited the Astrophysical Journal, which remains a major journal of astronomy today. Keeler was the first to observe the gap in Saturn's rings now known as the Encke Gap, using the 36-inch refractor at Lick Observatory on 7 January 1888.
