Astronomers see sun-like star with possible planet formation

AP Dec. 14, 2005

*************************
Astronomers have spotted a swirling
debris cloud around a sun-like star
that may be forming terrestrial
planets similar to Earth in a
process that could shed light on the
birth of the solar system. The star,
located 137 light years away,
appears to possess an asteroid belt,
a zone where the leftovers of failed
planets collide. Scientists...
