With her platinum blonde hair and a cherubic smile, Lois Riess looks in photos like what she is - a 56-year-old grandmother from small-town America.

Applying a novel technique that can yield new insight into dark energy in space, astronomers can now precisely measure the distance of stars up to 10,000 light-years away - 10 times farther than previously possible.

Three U.S.-born scientists won the Nobel Prize in physics on Tuesday for a study of exploding stars that discovered that the expansion of the universe is accelerating. The Royal Swedish Academy of Sciences said American Saul Perlmutter would share the 10 million kronor ($1.5 million) award with U.S.-Australian Brian Schmidt and U.S. scientist Adam ...
