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 ...

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, ...

Not all stars are created equally. Astronomers believe that the first stars to form after the Big Bang were mostly made of ...

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 ...

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 ...

When it comes to science, a simple observation can upend everything you think you know, such is the case with one star ...

Stellar size and class diversification originates from the initial mass of the molecular cloud from which stars form. The elemental composition of the molecular cloud, specifically the abundance of ...

A group of galaxies in our cosmic backyard has given astronomers clues about how stars form. A thorough survey using the NASA/ESA Hubble Space Telescope has observed around 14 million stars in 69 ...
