Using the XRISM space telescope, scientists spotted faint emissions of the elements in remnants of the Cassiopeia A supernova ...

We all know the universe contains a vast array of elements, ranging from light gases, such as helium, to heavy metals, like lead. But where did all of the elements come from? But the universe would ...

Scientists have made an exciting breakthrough in understanding how the universe creates the ingredients needed for life. A ...

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

Planets form more commonly in star systems with relatively high concentrations of elements heavier than hydrogen and helium, a new study suggests. Such heavier elements are necessary to form the dust ...

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 ...

The plutonium-244 hints at how heavy metals form in stars. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A rare version of the radioactive ...

Protons and neutrons come together to form the nuclei of simple elements: hydrogen, helium and lithium. It will take another 300,000 years for electrons to be captured into orbits around these nuclei ...

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing ...
