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

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

A new study suggests that the positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects. Neutron stars are the smallest, densest ...

In this video, we explore the origins of the first atom, tracing back to the big bang, where immense energy condensed to form ...

According to the classical model of nuclear structure, the internal structure of nucleons should not change if they are bound into atomic nuclei. But it was discovered 35 years ago that quarks inside ...

A new study identifies a transition in the strong nuclear force that illuminates the structure of a neutron star's core. Most ordinary matter is held together by an invisible subatomic glue known as ...

Right now, in our atmosphere, there are countless numbers of nitrogen atoms floating high above the Earth's surface. These atoms are, in a sense, vulnerable. Cosmic radiation, in the form of neutrons, ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...
