First, let's explore the atom's architecture. Formed from a cluster of protons and neutrons at the center of an atom, a nucleus is 10,000 times smaller than the atom as a whole, "like a fly in a ...

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

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

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 ...

While gluons are responsible for generating most of the visible mass in the universe, their role inside nuclei remains poorly ...

When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from ...

Together with results by some nuclear mass models (denoted by pink block), calculations suggest that the isospin asymmetry of heavy nuclei at the neutron drip line tends toward a saturation value ...
