![]() ![]() ![]() Operated by Georgia State University, the CHARA Array is an interferometer - a grid of telescopes so intimately linked that individual light waves from each one can be combined to achieve extremely high resolution overall. Meanwhile, another group using the same facility has discovered that red dwarfs, the most common stars in the universe, are significantly larger than was long thought.īoth groups used the CHARA (Center for High Angular Resolution Astronomy) Array: a Y-shaped layout of six 1-meter telescopes on Mount Wilson overlooking Los Angeles, California. They got readings that no one expected, but that turn out to put Vega's problems neatly in order. Using a linked array of telescopes to gain extremely high resolution, they measured brightnesses and temperatures across different parts of Vega's face. Familiar Vega, one of the brightest stars in the sky, has just yielded up a surprising secret about its true nature.Īstronomers have finally figured out the long-standing mystery of why Vega, the fifth-brightest star in the night sky, is brighter than it ought to be.
