The constellations
  • A collection of stars in which we can see a pattern
  • This idea is estimated to originate in pre-historic times
  • Easier to recognise that individual stars
  • The constellations can give us a map of the night sky

Slide 20 - Tekstslide

The life cycle of a star
  • Nebula — gets pulled together by it's own gravity
  • This starts a process called nuclear fusion (hydrogen turns into helium)
  • The main sequence
  • Red giant — white dwarf — black dwarf (invisible)
  • Super red giant — supernova — neutron star — black hole
