Life Cycle of A Star

What is the first stage of the life cycle of a star for all stars?

• nebula
• protostar
• main-sequence
• red giant

NGSS.HS-ESS1-3

This is a young star that glows as gravity brings it together

• Nebula
• Protostar
• Main-sequence star
• Red giant

NGSS.MS-PS2-4

In this stage, a star spends most of its life. Hydrogen is fused into helium at a temperature of millions of degrees.

• white dwarfs
• protostars

This stage is when a high mass star explodes

• Supergiant
• Red giant
• Supernova

NGSS.HS-ESS1-3

This stage is made by densely packed neutrons and sometimes spins and blinks and is called a pulsar

• Supernova
• White dwarf
• Black hole
• Neutron star

When a star's gravitational pull is so strong that not even light can escape, it's called a what?

NGSS.HS-PS1-8

What is the biggest difference between a protostar and a main sequence star?

• Protostars are more massive than main sequence stars
• Protostars do not engage in nuclear fusion
• Stars spend far longer in the protostar phase than their main sequence
• Protostars are hotter than main sequence stars
