During the initial stage of sunspot emergence and cooling, the formation of H2 may trigger a temporary “runaway” magnetic field intensification. The magnetic field prevents the flow of energy ...

While we have a clear picture of how the majority of H3+ is formed — a hydrogen molecule, or H2, colliding with its ionized counterpart, H2+ — scientists are keen to understand alternative ...

A balloon filled with helium and one filled with hydrogen are ignited. Hydrogen provides a loud explosion and flame. He(g) + O 2 (g) → N.R. Light the candle on the end of the yardstick and lower the ...
