  1. Interstellar molecules in the vacuum of space

  2. objective • Discuss the nature and significance of interstellar molecules.

  3. Interstellar space • Most of space is empty • Areas that aren't empty are filled with millions of tons of gas, and dust • Gas is primarily composed of Hydrogen, and smaller amounts of other molecular bits and pieces.

  4. What Does interstellar mean? • Interstellar means “in between stars” • The Interstellar Medium. • gas in ionic, atomic, and molecular form, dust, and cosmic rays

  5. Interstellar Molecules • Interstellar Molecules are the basic parts of every star • Over time, clouds of molecules gather in clouds. • Clouds eventually accrete and form the earliest parts of protostars • Over much more time, protostar forms a star, and begins burning

  6. Interstellar Odyssey • Many kinds of molecules can be found inside the vacuum of space. • And not all molecules eventually form stars. • There exists an interstellar cloud of nothing but pure alcohol. Raise your mug to that. • There are also many basic parts of amino acids in these clouds. • Some astrobiologists think that the foundations of life may have risen in these free-floating clouds of organic matter.

  7. Book • Average size of an atom is 10^-10 m across (or .1 nm) • REDDENING –Light is stripped of “blue” side of wavelength. • Extinction • Emission and Reflection nebulae
