Astronomers using the Hubble Space Telescope announced Thursday
that they are homing in on what they believe is a realistic estimate
of the age of the universe.
Beyond that question, calculations of the rate of expansion of the
universe dubbed the Hubble Constant also could help astronomers
predict its destiny.
Using measurements of pulsating stars called Cepheid variables
found in a cluster of galaxies 60 million light-years from Earth, the
astronomers calculated the universe's age at 9 billion to 12 billion
years.
The results come at a time when another group of Hubble
astronomers using a different technique calculated a slightly older
universe: 11 billion to 14 billion years.
