The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

A new method uses helium droplets combined with ultrashort laser pulses to trigger chemical reactions in a controlled way.

An atom consists of a ... but I'll talk about those soon. An element is what scientists call a group of atoms that are all the same, because they all have the same number of protons. Most of the ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has been getting bigger since the Big Bang. When the hydrogen and helium atoms ...

For the first time, a research team led by Markus Koch from the Institute of Experimental Physics at Graz University of Technology (TU Graz) has tracked in real time how individual atoms combine to ...

Second Major Helium Plant Planned For Southwest Wyoming Wyoming already produces 20% of the world’s Grade A helium supply from one plant east of Kemmerer. Now it’s about to get another major helium ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

So where did these elements go? Besides their abundance in the universe, what hydrogen and helium share is that they are both very light gases. That means they can easily escape the Earth's gravity.

Heavier elements, one atom at a time In 1955, mendelevium (101) was formed by bombardment of einsteinium-253 with a beam of helium-4 ions (alpha particles). The successful identification of ...

An atom of helium is a squirrel being chased by three or four sumo wrestlers across a soccer field. Spoiler alert: They will not catch the squirrel. Helium is light AF. Do you know why your balloons ...
