TUCSON, Jan. 9 (UPI) -- Vega, in northern night skies, has an asteroid belt much like our sun, a strong hint of yet-undiscovered planets orbiting other stars, U.S. astronomers say.
The discovery makes it more similar to its twin, a star called Fomalhaut, than previously known and both are now known to have inner, warm asteroid belts and outer, comet-filled belts, similar in architecture to the asteroid and Kuiper belts in our own solar system, researchers at the University of Arizona said.
