Parts of the Milky Way are much older than thought, study reveals

The Milky Way’s thick disk is 2 billion years older than astronomers previously thought and likely formed barely 800 million years after the Big Bang, a new study based on an unusual type of star found. 

Our galaxy can be split into two major parts: the thin disk, which holds the solar system and most of what we recognize as the Milky Way; and the much sparser, larger and older thick disk. To reconstruct the history of these components, a team of astronomers from the Max-Planck Institute for Astronomy in Heidelberg, Germany, looked at a population of stars in the Milky Way known as sub-giants.
