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 ...

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 ...

Observations of nearby red dwarf stars reveal rare carbon and oxygen isotopes, offering direct evidence of stellar nucleosynthesis and the chemical evolution of the Milky Way.

Stars form in the universe from massive clouds of gas. European Southern Observatory, CC BY-SA For decades, astronomers have wondered what the very first stars in the universe were like. These stars ...

Primordial nucleosynthesis during the early universe generated hydrogen, helium, and minor lithium-7 before the cosmos cooled, halting further fusion. Stellar interiors synthesize elements up to iron ...

Researchers have found that stars in the early universe may have formed from 'fluffy' molecular clouds. Using the ALMA telescope to observe the Small Magellanic Cloud -- whose environment is similar ...

Astronomers from The University of Western Australia’s node of the International Centre for Radio Astronomy Research (ICRAR) have developed a new way to study star formation in galaxies from the dawn ...

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 ...
