objective
objective
  • Discuss the nature and significance of interstellar molecules.
interstellar space
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.
what does interstellar mean
What Does interstellar mean?
  • Interstellar means “in between stars”
  • The Interstellar Medium.
      • gas in ionic, atomic, and molecular form, dust, and cosmic rays
interstellar molecules
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
interstellar odyssey
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.

  • 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
