Question

question 3 (1 point) according to the ihub chemistry materials, what do scientists specifically look for in outer space when trying to find life, and how do they detect it? a they look for molecules in outer space because molecules give off energy that scientists can detect. b they look for signs of intelligent communication and detect radio signals. c) they look for fossils on planetary surfaces and detect them with rovers. c they look for large celestial bodies and detect them with powerful telescopes.

Explanation:

Scientists search for life in outer - space by looking for molecules as they can emit detectable energy. Searching for intelligent communication (radio signals) is more about detecting intelligent life rather than life in general. Fossils on planetary surfaces are not a primary way to detect life in outer - space as most of space is not planetary surfaces and rovers have limited reach. Looking for large celestial bodies is not related to detecting life.

Answer:

A. They look for molecules in outer space because molecules give off energy that scientists can detect.
