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.

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

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

Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...

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

The helium and deuterium — a heavier form of hydrogen — nuclei formed even earlier, just a few minutes after the Big Bang, when the temperature was above 1 billion F (556 million C).

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 current AI race has reached a bottleneck that can be relieved only by new sources of electrical generation. Read more ...

Scientists believe Michigan may be an abundant source of what could become the next big thing in carbon-free energy.
