A collision between Earth and a massive Mars-sized protoplanet likely caused the formation of our moon. Now scientists from ...

The force of gravity varies across the solar system, primarily influenced by a celestial body's mass, size, and density. The Sun has the strongest gravity at the centre, while planets like Jupiter ...

In this video, we explore the existence of neutrons and their transformation into protons. We discuss why free neutrons are ...

Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

Nuclear physics is the study of the protons and neutrons at the centre of an atom and the interactions that hold them together in a space just a few femtometres (10-15 metres) across. Example nuclear ...
