  •   Study   Slideshow
  • Stars are formed from big clouds of gas and dust is known as:
    Nebula
  •  10
  • The main energy acting on a nebula at the beginning is:
    Heat
  •  10
  • A star is born when:
    a nebula turns into a protostar.
  •  10
  • A star that has ignited and has used up all of the hydrogen is called:
    Red Giant
  •  10
  • When the core of a Red Supergiant collapses, a bright event occurs, known as:
    supernova.
  •  10
  • After a supernova, the core can collapse into a neutron star, or if massive enough it can become a:
    black hole
  •  10
  • When a red giant's outer atmosphere drifts away releasing elements to space is now known as:
    planetary nebula
  •  10
  • One possible outcome that is left after a supernova is a super dense core called a:
    neutron star.
  •  10
  • A black hole is black because:
    even light cannot escape its gravity.
  •  10
  • Our sun is currently in what star stage?
    Main sequence
  •  10
  • Main sequence stars are made primarily of which elements?
    H and He
  •  10
  • When a nebula condenses, takes on a shape, and emits light is called:
    T-Tauri
  •  10
  • Why won't our sun ever become a black hole?
    It is too small.
  •  10
  • The stable and longest lasting period of a star’s life cycle is called:
    Main Sequence
  •  10
  • What fuel do main sequence stars use?
    H
  •  10
  • If our Sun died out, what would it become at the end?
    White dwarf
