Gravity pulls gases and dust particles in space toward one another, squeezing them into a smaller and smaller space. The temperature at the center rises high enough for nuclear fusion of hydrogen to begin.
What stage in a stars life cycle is this describing? 

• The birth of a star
• The death of a star
• Black Hole
• Stellar Nebula

NGSS.HS-ESS1-3

A relatively small, dense star at the end of its life cycle, which generates little or no energy and has contracted to its densest state.
What stage in the life cycle does this describe? 

• Black Hole
• Nebula
• White Dwarf
