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

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

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 ...

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

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 ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses. They definitely exist in East Lansing, Michigan. The Facility for Rare ...

We may have finally seen the first generation of stars. Astronomers have been looking for these primordial behemoths, called Population III stars, for decades. Now they have found what may be the most ...

In an ejection that would have caused its rotation to slow, a magnetar is depicted losing material into space in this artist’s concept. The magnetar’s strong, twisted magnetic field lines (shown in ...
