A giant, gaping hole that opened up in the Sun's atmosphere has been identified as the source of a surprising abundance of a rare isotope of helium. In late October 2023, the Sun was recorded belching ...

There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is ...

Theoretical calculations predict a complex excited state (0+) for helium-4 (4He) at the 20.21 MeV energy level. This state involves a coupling of three cluster configurations: hydrogen-3 and a proton, ...

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 ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

A photon is absorbed by the ground state of helium-4. This excites the transition to the first excited state of helium-4, which sits just above the energy threshold for separation into a proton and a ...

Helium nanodroplets offer a unique medium for realising and exploring quantum fluid behaviour at ultralow temperatures. These nanoscale clusters of helium atoms, which exist in a superfluid state ...
