Multiple choice

What is the most common method used to detect molecules in space?

  1. Radio astronomy

  2. Infrared astronomy

  3. X-ray astronomy

  4. Ultraviolet astronomy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Radio astronomy is the most common method used to detect molecules in space because it allows astronomers to study the rotational and vibrational transitions of molecules.

Multiple choice

What is the role of molecules in the formation of stars and planets?

  1. They provide the raw material for star and planet formation.

  2. They cool the gas and dust in molecular clouds, allowing them to collapse and form stars.

  3. They provide a means for the transport of angular momentum away from the forming star.

  4. All of the above.
