Definition: The collection of all galaxies in the universe, representing the largest scale of cosmic structure.

Example: Astronomers study the metagalaxy to understand the formation and evolution of the universe.

Definition: A small piece of rock or metal from space that burns brightly when it enters the Earth's atmosphere, creating a streak of light in the sky.

Example: Last night, I saw a meteor streak across the sky during the meteor shower.

Definition: In a way that is very rapid or sudden, like a meteor moving through the sky.

Example: Her career took off meteorically after she won the award.

Definition: A piece of rock or metal from space that survives its journey through the atmosphere and lands on Earth.

Example: Scientists study meteorites to learn more about the early solar system.

Definition: Relating to or characteristic of meteorites, which are fragments of rock or metal that fall to Earth from space.

Example: The meteoritic material found in the crater provided valuable information about the origins of the solar system.

Definition: Relating to meteorites, which are rocks from space that fall to Earth.

Example: The meteoritical study of the samples provided insights into the formation of our solar system.

Definition: The field of study that focuses on meteors and meteorites, including their composition, origin, and impact on Earth.

Example: Meteoritics is essential for understanding the history of our solar system.

Definition: A small solid object that travels through space, smaller than an asteroid and larger than a dust particle.

Example: The meteoroid entered the Earth's atmosphere and created a bright streak of light in the sky.

Definition: Relating to small celestial bodies that enter the Earth's atmosphere and become meteors.

Example: The meteoroidal fragments were studied to understand their composition.

Definition: A state where the force of gravity is very weak, often experienced in space, making objects feel weightless.

Example: Astronauts conduct experiments in microgravity to study how living organisms behave without the effects of gravity.
