Steward Observatory history, and today it is telling us facts, forever wonderful, about the size of our universe; perhaps tomorrow it will give us practical help in showing us how to predict climatic conditions in the future. Steward Observatory manages three different observing locations in southern Arizona: Mount Graham International Observatory (MGIO), Mount Lemmon Observatory, and Catalina Station on Mount Bigelow. It also operates telescopes at two additional important observatories: Kitt Peak National Observatory (KPNO) and Fred Lawrence Whipple Observatory on Mount Hopkins. Steward is a partner in the Sloan Digital Sky Survey-III, which is located in New Mexico at Apache Point
Lowell, Massachusetts is River Meadow, or Hale's Brook. This brook flows largely in a man-made channel, as the Lowell Connector was built along it. Both of these minor streams have limited industrial histories as well. The bordering towns (clockwise from north) are Dracut, Tewksbury, Billerica, Chelmsford, and Tyngsborough. The border with Billerica is a point in the middle of the Concord River where Lowell and Billerica meet Tewksbury and Chelmsford. The ten communities designated part of the Lowell Metropolitan area by the 2000 US Census are Billerica, Chelmsford, Dracut, Dunstable, Groton, Lowell, Pepperell, Tewksbury, Tyngsborough, and Westford, and Pelham, NH.
