A New Way To Measure Cosmic Distances
Pasadena CA (SPX) Jun 09, 2009 - Ohio State University researchers have found a way to measure distances to objects three times farther away in outer space than previously possible, by extending a common measurement technique. They discovered that a rare type of giant star, often overlooked by astronomers, could make an excellent signpost for distances up to 300 million light-years - and beyond.
