NOAO -- Strong darkening observed around the equator of Vega suggests that the fifth brightest star in Earth's sky has a huge temperature difference of 4,000 degrees Fahrenheit from its cool equatorial region to its hot poles. Models of the star based on these observations suggest that Vega is rotating at 92 percent of the angular velocity that would cause it to physically break apart, an international team of astronomers announced today in Washington, DC, at the 207th meeting of the...

ATLANTA -- For decades, scientists have observed that Regulus, the brightest star in the constellation Leo, spins much faster than the sun. But thanks to a powerful new telescopic array, astronomers now know with unprecedented clarity what that means to this massive celestial body. A group of astronomers, led by Hal McAlister, director of Georgia State University's Center for High Angular Resolution Astronomy, have used the center's array of telescopes to detect for the first time Regulus'...

Mount Wilson Observatory -- astronomical observatory located in California on Mt. Wilson, near Pasadena. Mt. Wilson Observatory was founded in 1904 by George E. Hale. Its equipment includes 100-in. (2.5-m) and 60-in. (1.50-m) reflecting telescopes and two solar-tower telescopes 150 ft. (46 m) and 60 ft. (18 m) in length. The most recent addition is the CHARA (Center for High Angular Resolution Astronomy) array operated by Georgia State Univ.; it consists of six 39-in. (1-m) aperture...
