The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new ...

Astronomers have discovered a surprisingly "pristine" red giant with the lowest concentration of heavy elements ever seen in ...

Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of only hydrogen and helium with trace amounts of lithium, as the heavier ...

Astronomers studying how elements heavier than iron were produced in the early Milky Way have identified a distinct series of epochs of galaxy-wide chemical formation. This evolutionary timeline, ...

Besides being a point of light, a star is a luminous, spherical mass of plasma, enough to hold itself together under its own gravity. On its own, though, gravitational rounding isn't enough. What ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

How can timing influence planetary formation and evolution? This is what a recent study published in The Astrophysical ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...
