Astrobiology is the interdisciplinary field that combines the study of astronomy, biology, geology, and chemistry to explore the origin, evolution, and distribution of life in the universe.

An exoplanet is a planet that orbits a star other than the Sun. As of 2023, there are over 5,000 confirmed exoplanets, with many more candidates awaiting confirmation.

Habitability refers to the ability of a planet or moon to support life. This includes factors such as the presence of liquid water, a stable atmosphere, and a suitable temperature range.

Life detection refers to the process of detecting and characterizing life beyond Earth. This can be done through a variety of methods, such as analyzing the composition of a planet's atmosphere, searching for biosignatures, or sending robotic missions to explore other worlds.

Water is essential for life as we know it. It is a solvent for many biochemical reactions, and it helps to regulate temperature and transport nutrients.

Abiogenesis is the process by which life originated from non-living matter. This is a complex and poorly understood process, but it is thought to have occurred in the early history of Earth.

Paleontology is the study of the history of life on Earth. This includes the study of fossils, which are the preserved remains or traces of ancient organisms.

The Chicxulub Impact is thought to have caused the extinction of the dinosaurs. This impact occurred 66 million years ago in what is now the Gulf of Mexico.

Cosmology is the study of the origin and evolution of the universe. This includes the study of the Big Bang, the formation of galaxies and stars, and the ultimate fate of the universe.

Geology is the study of the composition and structure of the Earth's interior. This includes the study of rocks, minerals, and fossils.

Biochemistry is the study of the chemistry of living organisms. This includes the study of proteins, carbohydrates, lipids, and nucleic acids.

Ecology is the study of the interactions between living organisms and their environment. This includes the study of food webs, ecosystems, and biodiversity.

Evolutionary biology is the study of the evolution of life on Earth. This includes the study of natural selection, adaptation, and speciation.

Anthropology is the study of the origin and evolution of humans. This includes the study of human culture, language, and biology.

Environmental studies is the study of the relationship between humans and the environment. This includes the study of pollution, climate change, and resource management.
