What is the term used to describe the study of chemical processes in space?

  1. Astrobiology

  2. Astrochemistry

  3. Astrophysics

  4. Cosmochemistry


Correct Option: B
Explanation:

Astrochemistry is the study of chemical processes in space, including the formation and evolution of molecules in interstellar clouds, the atmospheres of planets, and other celestial objects.

Which molecule is considered to be a key biosignature in the search for extraterrestrial life?

  1. Oxygen

  2. Water

  3. Methane

  4. Carbon Dioxide


Correct Option: B
Explanation:

Water is considered to be a key biosignature because it is essential for life as we know it and is relatively abundant in the universe.

What is the term used to describe organic molecules that are found in extraterrestrial environments?

  1. Astrobiology

  2. Astrochemistry

  3. Astrophysics

  4. Exobiology


Correct Option: D
Explanation:

Exobiology is the study of organic molecules and life in extraterrestrial environments.

Which interstellar molecule is considered to be a precursor to the formation of amino acids?

  1. Formaldehyde

  2. Methane

  3. Hydrogen Cyanide

  4. Carbon Monoxide


Correct Option: C
Explanation:

Hydrogen cyanide is considered to be a precursor to the formation of amino acids, which are the building blocks of proteins.

What is the name of the space telescope that was launched in 2009 to study the composition of exoplanet atmospheres?

  1. Hubble Space Telescope

  2. James Webb Space Telescope

  3. Spitzer Space Telescope

  4. Kepler Space Telescope


Correct Option: B
Explanation:

The James Webb Space Telescope is a space telescope that was launched in 2009 to study the composition of exoplanet atmospheres.

Which molecule is considered to be a potential sign of microbial life on Mars?

  1. Methane

  2. Oxygen

  3. Water

  4. Carbon Dioxide


Correct Option: A
Explanation:

Methane is considered to be a potential sign of microbial life on Mars because it is a product of biological processes and is not easily produced by non-biological processes on the Martian surface.
