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 ...

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

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, ...

This festive season, as we adorn ourselves with gold and silver, few realise that these precious metals were born in the ...

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 ...

A surprising new study reveals that the first stars appeared in a pre-heated universe, challenging earlier ideas about early cosmic conditions.

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 ...

Giant flares blasted out of supermagnetized stars called "magnetars" could forge planets' worth of gold and other heavy elements such as platinum and uranium. This is the conclusion of an ...

"We were surprised that water could actually form so early on — even before the birth of the first galaxies." When did life as we know it first emerge in the universe? We don’t know for sure, but the ...

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected. This article was originally published at The Conversation. The publication ...
