What is a interstellar cloud made of?

Since interstellar clouds are most often overdensities in the interstellar medium, they have overwhelmingly similar chemical compositions - most of them (about 90%) being hydrogen, although this may be molecular, or ionized (plasma), with most of the remainder being helium. Heavier elements and compounds have been discovered spectroscopically in interstellar clouds, including more recently some unexpected light organic molecules.


What is the most abundant molecule in interstellar clouds besides molecular hydrogen?

The most abundant molecule in interstellar clouds besides molecular hydrogen is carbon monoxide (CO). It is frequently used by astronomers as a tracer for studying the presence of molecular clouds and star formation activities.

What colors of light passes most easily through interstellar clouds?

Red light passes most easily through interstellar clouds because it has the longest wavelength and lower energy, making it less likely to be absorbed or scattered by dust particles within the cloud. Blue and violet light, with shorter wavelengths and higher energy, are more likely to be scattered or absorbed.


What type of clouds are most common in a hurricane?

Cumulonimbus clouds are most common in hurricanes. These clouds are large, dense, and capable of producing heavy rainfall and thunderstorms. They are characteristic of the intense convection and strong updrafts found in hurricanes.

Are most molecules found in the giant molecular clouds are based on silicon?

No, most molecules found in giant molecular clouds are not based on silicon. Instead, they are primarily composed of elements like hydrogen, helium, carbon, oxygen, and nitrogen, which are more abundant in the universe. Silicon-based molecules are less common in interstellar environments.
