1
What is made out of gas and dust and is distributed throughout our galaxy?
- Interstellar Matter
- Interstellar Reddening
- Reflection Nebula
- Spin Flip Radiation
2
We study interstellar matter because:
- It fills space with ultra violet light and such light destroys molecules leaving behind interstellar matter
- It has everything to do with stars: stars are made of it, contribute to it, and there's a lot of it
- It includes water, alcohol, methane, ammonia and many complex molecules that form the basis of life here on the earth and most likely elsewhere
- It becomes electrically charged in space and then acts to attract atoms. Such atoms can then slowly form complex molecules on the grains over millions of years.
