What makes one star different from another
What makes one star different from another?

  • Mass determines lifespan of star

  • Flame demonstration: predict on left side order from coolest to hottest.

Neutron star or black hole
Neutron Star or Black Hole?

Black Hole

If the star is at least 9 or more times larger than the Sun, the core will continue to collapse into a black hole, an extremely dense area with a strong gravitational pull that light can not escape.

  • Neutron Star

  • If the star is at least 1.5 but less than 9 times larger than the Sun, the core left after the supernova will collapse into a neutron star. This is a star composed only of neutrons.


Types of galaxies quasars
Types of Galaxies – Quasars…

  • A quasar is a distant galaxy with a black hole at its center.

  • As enormous amounts of gas revolve around a black hole, the gas heats up and shines brightly.
