Do we live in a supernova graveyard? A team of researchers proposes that 10 million years ago two giant neutron stars crashed ...

Hycean worlds, which are a possible kind of exoplanet with deep oceans surrounded by a thick envelope of hydrogen, could ...

Plutonium discovered at the bottom of the ocean was found to be refuse from a kilonova that exploded close to Earth 10 ...

Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have found a ...

Scientists at Oak Ridge National Laboratory have developed an isotope tracking method driving molten salt reactor innovation.

The trailblazing Harvard scientist, who documented the dominance of hydrogen and helium in stars, is still inspiring ...

Scientists have acquired direct evidence of rare, pulsing pear-shaped structures within atomic nuclei of the rare-earth element Gadolinium, thanks to new research.

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

In the past three years, astronomers have discovered a mysterious new type of radio source. We call these long-period transients. An international team of astronomers led by scientists from the ...

The discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed.

Abstract: We investigate the radiation and temperature effects on the performance of carbon and aluminum-coated silica-based optical fibers that are designed to prevent the diffusion of hydrogen into ...

By far the most common is helium-4, with a nucleus containing two protons and two neutrons. Helium-4 accounts ... Helium isn't the only element with a primordial isotope, either; hydrogen, the ...
