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. Along the way, they also learned something new about how these stars evolve. (source: sciencedaily.com)
