The results indicate that the elements essential for life formed within extreme, highly energetic environments deep inside ...

XRISM observations of Cassiopeia A reveal abundant chlorine and potassium, showing supernovae can forge these life-linked ...

Researchers at the Argonne National Laboratory studied a nuclear reaction and measured conditions that can explain how heavy elements are formed inside stars. Stars are mainly composed of light ...

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 ...

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 ...

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 ...

In the dense environment of the early universe, dark matter particles would collide with, and annihilate, each other, ...

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 ...

Scientists believe that many of the elements found in the Universe that are heavier than iron are created when stars merge or explosively die, but they are still unsure about the cosmic origin of ...

"Even today, our understanding of star formation is still developing; comprehending how stars formed in the earlier universe is even more challenging." When you purchase through links on our site, we ...

How heavy can an element be? An international team of researchers has found that ancient stars were capable of producing elements with atomic masses greater than 260, heavier than any element on the ...

Even if early Earth had water and oxygen, the planet would still have needed another ingredient for life to flourish: heavy metals. Our cellphones, Earth’s core and even human metabolism would ...
