Essential concepts and terminology to understand this topic
A luminous ball of gas, primarily hydrogen and helium, held together by gravity and powered by nuclear fusion.
A vast cloud of gas and dust in space, often the birthplace of stars.
The process where hydrogen nuclei combine to form helium, releasing energy and powering stars.
The phase in a star's life where it fuses hydrogen in its core, representing most of its lifespan.
A massive explosion marking the end of a massive star's life, often leading to the formation of neutron stars or black holes.
A dense, compact remnant of a low- to medium-mass star that has exhausted its nuclear fuel.
A small, incredibly dense star composed almost entirely of neutrons, formed after a supernova.
A region of space where gravity is so strong that nothing, not even light, can escape it.
A late stage in a star's life when it expands and cools after exhausting the hydrogen in its core.
A graph that plots stars based on their luminosity and temperature, used to study stellar evolution.
The creation of heavier elements through nuclear fusion within stars.
A system where two stars orbit a common center of mass.
The distance light travels in one year, approximately 9.46 trillion kilometers.
The range of all types of electromagnetic radiation, including visible light and other wavelengths emitted by stars.
The contraction of a massive object due to the force of gravity, often leading to star formation.
