ITHACA, N.Y. - Using light from the Big Bang, an international team led by Cornell University and the U.S. Department of Energy s Lawrence Berkeley National Laboratory has begun to unveil the material which fuels galaxy formation. There is uncertainty on the formation of stars within galaxies that theoretical models are unable to predict, said lead author Stefania Amodeo, a Cornell postdoctoral researcher in astronomy in the College of Arts and Sciences, who now conducts research at the Observatory of Strasbourg, France. With this work, we are providing tests for galaxy formation models to comprehend galaxy and star formation.

In 2013, the Hubble Space Telescope found the birth certificate of oldest known star in the universe, cataloged as HD 140283, aptly named “methuselah”. The star, located in the constellation Libra, which is at the very first stages of expanding into a red giant, could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe’s calculated age of about 13.8 billion years, creating what we commonly call a dilemma.
The strange star, said NASA’s Hubble team, which has an anemic 1/250th as much of the heavy element content of our sun and other stars in our solar neighborhood.)has been known about for more than a century because of its fast motion across the sky. The high rate of motion is evidence that the star is simply a visitor to our stellar neighborhood. Its orbit carries it down through the plane of our galaxy from the ancient halo of stars that encircle the Milky Way, and will eventually slingshot back
