Characteristics of the Universe Study Guide
Supernova – a gigantic explosion where this massive star collapses and sheds its outer layers into space
Neutron Star – a star that has collapsed under gravity and the electrons and protons get smashed together to form neutrons
Black hole- an object so massive and dense light cannot escape it
Pulsar – a rapidly spinning neutron star that emits rapid pulses of radio and optical energy
White Dwarf - a small, hot, dim star leftover from an old star
H-R Diagram – a graph that shows the relationship between a star’s temperature and absolute magnitude
Red Giant – A large, reddish star late in its life cycle
Main Sequence – where most stars are located on the H-R diagram
- What size star is the sun? It is a medium sized star
- What pulls together the gas and dust to make a star? gravity
- What is nuclear fusion? When hydrogen turns into helium
- What information does the H-R diagram give us? Be prepared to draw/plot certain color stars on an H-R diagram. Also be prepared to show where the main sequence stars are found.
- Know stages in order for a medium/average star.
- What is the big bang theory? Theory that the universe began with a huge explosion
- What is cosmology? The study of the universe
- Is the Universe still moving today? Yes – it is expanding.
- What do Scientists think will happen to the Universe in the future? That is will just continue to expand forever.
- Know the three different types of galaxies. Be prepared to draw a sketch and give defining characteristics of each.
Spiral – disc shaped (Milky Way)
Elliptical – oval shaped
Irregular – no definite shape
