What stage fills in the blank. Nebula --> Main sequence --> red giant --> ______________ --> white dwarf --> black dwaft

• supergiant

• planetary nebula

• black hole

• supernova

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

• Nebula

• Protostar

• Main-sequence star

• Red giant

Low mass stars expand into what after using up the hydrogen in their core

• red giants

• supergiants

• white dwarfs

• protostars

This stage is when a high mass star explodes

• Supergiant

• Red giant

• Supernova

• Black hole

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?

• Black hole

• Supernova

• White dwarf

• Nebula

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

Our sun is known as a middle-aged, stable star. Also known as a ____________________.

• Gas Giant

• Nebula

• Pulsar

• Main Sequence Star
