Helium-3 discovery in Minnesota is sparking big energy claims, but the science, rarity, and real-world limits matter more ...

When theoretical physicists like myself say that we’re studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan’s Subaru telescope has revealed ...

When humans traveled to the moon, large quantities of a very rare gas known as helium-3 were extracted. Until then, it was ...

POSITIVELY charged hydrogen atoms with velocities acquired by falling through 300 to 900 volts have been found to possess an unexpected range in helium and other gases. With helium pressures so high ...

Galactic cosmic rays (GCRs) are energetic particles traveling across the Galaxy as high-energy beams, and are a unique probe to explore the astrophysical particle accelerators and the interstellar ...

Inside the nucleus of some atoms, protons appear to be doing very unexpected things. They are pairing up far more often than usual when they get extremely close to each other, and physicists don’t ...

When people talk about evidence for the Big Bang, they’re most likely to point to the Cosmic Microwave Background. But there’s another major piece of evidence that the Big Bang happened, and it ...

The methods previously described have been applied to a study of the elastic scattering of 4· 2 MeV protons by deuterium, helium, nitrogen, oxygen, neon, argon, chlorine and bromine. The results ...

Which is your favourite chemical element? To mark the International Year of the Periodic Table, our science journalists will be arguing for their pick from the 118 known elements. In this instalment, ...
