How Old is the Milky Way ? Eso0425 — Science Release VLT Observations of Beryllium in Two Old Stars Clock the Beginnings 17 August 2004 Observations by an international team of astronomers [1] with the UVES spectrometer on ESO's Very Large Telescope at the Paranal Observatory (Chile) have thrown new light on the earliest epoch of the Milky Way galaxy. The first-ever measurement of the Beryllium content in two stars in a globular cluster (NGC 6397) - pushing current astronomical technology towards the limit - has made it possible to study the early phase between the formation of the first generation of stars in the Milky Way and that of this stellar cluster.
The age of the Milky Way How old is the Milky Way? Globular clusters and the ages of stars Modern astrophysics is capable of measuring the ages of certain stars, that is the time elapsed since they were formed by condensation in huge interstellar clouds of gas and dust. Still, those cluster stars were not the first stars to be formed in the Milky Way. Notes. New Discovery about the Fabric of Space-Time.

The theory that everyone and everything on Earth contains minuscule star particles dates back further than Moby's popular 2002 song "We Are All Made of Stars. " In the early 1980s, astronomer Carl Sagan hosted and narrated a 13-part television series called "Cosmos" that aired on PBS. On the show, Sagan thoroughly explained many science-related topics, including Earth's history, evolution, the origin of life and the solar system. "We are a way for the universe to know itself. Some part of our being knows this is where we came from. His statement sums up the fact that the carbon, nitrogen and oxygen atoms in our bodies, as well as atoms of all other heavy elements, were created in previous generations of stars over 4.5 billion years ago. "All organic matter containing carbon was produced originally in stars," Impey told Life's Little Mysteries.
How star stuff got to Earth When it has exhausted its supply of hydrogen, it can die in a violent explostion, called a nova. Cosmic connections.
