Question 3What are Herbig-Haro Objects?
  1. A special type of open star clusters with very
    young stars.
  2. Galaxies with very active star formation.
  3. Protostellar disk with bipolar outflows (jets).
  4. Dense pockets of gas which might very soon
    contract to form stars.
  5. Very massive stars that can trigger further star
    formation.
