Lowell Observatory

It's a one-of-a-kind fusion of research and outreach, a 4.2-meter telescope rising seven stories above the top of a cinder cone forty miles from Flagstaff. Lowell Observatory and Discovery Communications are building this $44 million facility to push the frontier of knowledge – and to bring the marvels of the cosmos to millions. In advanced stages of construction, the DCT will see first light in 2011, with exciting science to follow. Learn more about the DCT

High-resolution astronomy with the Navy Prototype Optical Interferometer

The Navy Prototype Optical Interferometer (NPOI) is a collaborative project between the United States Naval Observatory, the Naval Research Laboratory, and Lowell Observatory. The interferometer stretches across half a kilometer of Lowell's dark-sky site at Anderson Mesa near Flagstaff, and can measure the positions of stars with extraordinary precision. Read more at the NPOI home page or take an interactive tour to learn how it works.

Lowell astronomer Henry Roe and his colleagues have found a new tropical storm – 800 million miles away in the atmosphere of Saturn's moon Titan

Their paper, "Storms in the Tropics of Titan," was published in the August 13, 2009, issue of Nature. Henry and his colleagues observed a huge storm with hemisphere-wide effects. "It was as though we observed a giant storm covering South Africa that days later caused clouds to form over Antarctica and Indonesia," said collaborator Emily Schaller. "These observations show that the channels and streambeds in Titan's tropical desert can be explained by infrequent but strong downpours, much like many of the landforms here in the Southwestern United States," added Roe.
