3 True/False Questions

1. magnitude → an immense cloud of gas (mainly hydrogen) and dust in interstellar space

   True        False

2. neutron star → young star; stage that occurs after nebula after cloud shrinks and heats up; continues to gain mass becaus of gravitational pull, heat makes it glow

   True        False

3. protostar → young star; stage that occurs after nebula after cloud shrinks and heats up; continues to gain mass becaus of gravitational pull, heat makes it glow

   True        False
