Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Astrochemistry?Abundance, formation, reactions, and radiation interactions of molecules in cosmic environments
2. What is the discipline domain?Interdisciplinary science at the intersection of astronomy and chemistry
3. What is the observational tools?Spectroscopy (optical, UV, radio, infrared), laboratory experiments, and theoretical modeling
4. How do scientists find molecules in space?They use special tools called spectroscopes that split light into colors. By looking at the fingerprints of light, they can see which molecules are there.
5. Why are cold clouds in space important for making stars?Cold, dense clouds are where new stars and planets start. The molecules inside these clouds help the gas collapse and form new suns.

Interstellar Medium (ISM): The matter and radiation existing in the space between stars, comprising gas and dust.
Molecular Clouds: Dense, cold regions within the ISM where stars and planets form, rich in molecular species.
Spectroscopy: The study of the interaction between matter and electromagnetic radiation, used to identify chemical composition and physical conditions.
Cosmochemistry: The study of the chemical composition of celestial bodies and the processes that led to their formation.
