Until now, there have been no good ideas as to what formed these bizarre "cycloidal" features. Now, planetary scientists at the University of Arizona in Tucson provide a model for how these features are created. It is perhaps the most convincing evidence yet for a global ocean.

A team at Steward Observatory of the University of Arizona has built the first true detector arrays for the far infrared. These arrays will be mounted into an instrument for the Space Infrared Telescope Facility (SIRTF), a major NASA observatory to be launched in late 2001.
University of Arizona doctoral student Barry B. Goeree and UA senior Brian Shucker placed first in the student paper competition at the 13th Annual American Institute of Aeronautics and Astronautics/ Utah State University Conference on Small Satellites held Aug. 23-26 in Logan, Utah.
The UA and the Australian National University have agreed to refurbish a little-used telescope at the Siding Spring Observatory (near Coonabarabran) with modern detectors and computers to carry out a search for potentially hazardous asteroids.
During the past 30 years, microchip companies have developed manufacturing processes by combining some understanding of their underlying physics and chemistry with a tremendous amount of iterating. Engineers call this kind of educated guessing the "Edisonian Approach."
Scientists are delighted with photos of Earth's moon snapped by cameras aboard the Cassini spacecraft during its recent Earth flyby. The test was conducted Aug.18 (GMT), when Cassini flew more than 700 miles over the Pacific Ocean.
University of Arizona alumnus John Lombardi has won one of the 1999 R&D 100 Awards, which have been called "the Nobel Prizes of Applied Research." He developed the material called Aqua-Port, which allows engineers to construct complex shapes that could be produced in no other way.
Chemists at the University of Arizona in Tucson may be closer than ever to stopping HIV (human immunodeficiency virus). They are using a unique approach based on understanding the interactions of the virus with cells at the most fundamental, molecular level.
The University of Notre Dame announced today that it has joined the Large Binocular Telescope (LBT) project. With this new relationship, Notre Dame becomes the third U.S. university system involved in the project, along with the University of Arizona and Ohio State University.
