• the earliest stage of a star's life

• red super giant explodes

Answer explanation

Black Dwarf

• The remains of a high mass star

• Exerts such a strong gravitational pull that no light escapes

• The star left at the core of a planetary nebula

Answer explanation

At which point in its development does a star exit the protostar stage and become a main sequence star?

• When the nuclear fusion process begins

• When collisions in particles result in an increase of temperature

• When gravity squeezes it making it more dense

• When it gets bigger and gravity gets stronger causing it to collide more often
