The brilliant white-hot A type star Vega is the fifth brightest star in the night sky.  Pronounced Vee-gah, this star has another surprise.  When astronomers observed Vega with the infrared observatory satellite IRAS, they learned that it produced more light at longer infrared than expected.  Further study led astronomers to believe this excess was from a ring of dust orbiting Vega at a distance of 80 astronomical units.  This was a momentous discovery because the dust may have led to planets or could still lead to planets.  In support of this theory, IRAS detected no dust near the star.  Possibly, planets could of swept the inner part of the solar system clean!
