Number of Undiscovered Near-Earth Asteroids Revised Downward



Provo, UT (SPX) Oct 18, 2017
Fewer large near-Earth asteroids (NEAs) remain to be discovered than astronomers thought, according to a new analysis by planetary scientist Alan W. Harris of MoreData! in La Canada, California. Harris is presenting his results this week at the 49th annual meeting of the American Astronomical Society's Division for Planetary Sciences in Provo, Utah. Observers have been cataloging potentially hazardous asteroids for decades. Based on the number of finds, the area of sky explored, and the limiting b ... read more

Saturn's A ring contained by not one, but seven moons
(UPI) Oct 17, 2017
Until recently, astronomers assumed Saturn's A ring was contained by a single moon, Janus, the gas giant's largest. But new research shows the A ring, the outermost of Saturn's large, bright rings, is confined by seven moons. ... more
