Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Many space-lovers know the phrase "We are all made of star stuff." And it's true - our planet formed from the dust cloud left ...

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 ...

Physicists, who dedicate their lives to studying the topic, don’t actually seem to like physics very much since they’re always hoping it’s broken. But we’ll have to forgive them; finding out that a ...

Supernovae have produced nearly every element occurring in nature. When a star is born, it is because it has enough mass to create enough heat, gravity and pressure to sustain nuclear fusion. Fusing ...

Suppose you were to look all around the universe and count all the different elements. What would you find? Well, you would find a whole bunch of hydrogen and helium. But there is also quite a bit of ...

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 ...

Our planet’s core is made mostly of iron, but it might also contain primordial helium that formed just after the Big Bang. Helium normally has trouble bonding with other elements, but researchers were ...

Look, no one said building a large harvester to roam around the Moon and sift through hundreds of tons of regolith to retrieve small amounts of helium-3 would be easy. And that’s to say nothing of the ...
