Hydrogen in molecular form, H₂, is thought to be very abundant in gas clouds in space, but these molecules emit radiation relatively inefficiently since they are symmetrical. Which other molecular element occurs in close association with H₂ and is used as a probe for molecular clouds?

Question

Quizplus · Accepted Answer

Carbon monoxide (CO) is often used as a probe for molecular clouds in space because it emits radiation more efficiently than molecular hydrogen (H₂), allowing astronomers to infer the presence of H₂.
