NASA SCIENTISTS IDENTIFY SMALLEST KNOWN BLACK HOLE
--------------------------------------------------
Using a new technique, two NASA scientists have identified the lightest
known black hole. With a mass only about 3.8 times greater than our Sun
and a diameter of only about 15 miles, the black hole lies very close to
the minimum size predicted for black holes that originate from dying
stars.
