  • They range in size from millions of miles across to hundreds of light years across.
  • Nebulas are mostly composed of hydrogen along with smaller amounts of other gases and dust particles.
  • Stars and planetary systems are formed from the gas and dust within nebulae.
  • The Orion Nebula is the closest star forming region to Earth, it lies 1,300 light years away and is thought to be around 25 light years across.
  • Nebulae which exist outside the Milky Way are known as extra-galactic nebulae.
