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.

It took some detective work, but they think they know what was the cause. The MRI machine uses liquid helium to cool its powerful magnets. Turns out the helium had leaked and over 5 hours about ...

Helium, a colourless, odourless, and non-toxic inert gas is the second most common element in the universe. Despite its abundance in space, helium is a finite resource here on Earth, found only in ...

Our lives are surprisingly dependent upon this extremely light and unreactive gas, yet supplies of it are remarkably fragile. Nancy Washton remembers the sinking feeling she got when she heard her ...

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. Primordial helium from the ...

First of all, we'd better look at how balloons are released. When helium filled balloons are handed out at public events, they usually come with a piece of string or ribbon attached. The ...

Hydrogen and helium separate at pressures and temperatures ... Senior physics writer Emily Conover has a Ph.D. in physics from the University of Chicago. She is a two-time winner of the D.C ...

But Interlune’s aims aren’t purely scientific—they want to mine the moon’s possible trove of helium-3 isotopes. Helium-3’s utility comes from its single neutron, which allows it to cool ...
