A method used to determine the age of an object containing organic material by measuring the amount of Carbon-14 it contains.

Approximately 5730 years, which is the time it takes for half of the Carbon-14 in a sample to decay.

The leading explanation about how the universe began, stating that it was formed from a singular explosion that caused its expansion.

A late stage in a star's life cycle when it has exhausted its hydrogen fuel and begins to fuse helium, causing it to expand.

The process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy, which powers stars like the Sun.

A graph that plots stars' brightness against their temperature, helping to classify stars and understand their evolution.

Temperature, brightness (luminosity), and color.

A supernova is a powerful and luminous explosion of a star, marking the end of its life cycle.

A region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

A small, dense star that is the remnant of a star that has exhausted its nuclear fuel and shed its outer layers.
