Giant and Supergiant Stars•4-70 times the mass of the Sun
•Short life spans

Stars that go Nova
• Only occurs in binary systems
• A star can go Nova several times

Neutron Stars
•1 teaspoon of it’s matter would weigh a billion tons on earth
•Rotates 10-100 times per second
•1 solar flare releases 100 times the energy the sun does in a year

Black Holes •Remains of a supernova star with a mass at least 10 times that of the sun
•The Black hole at the center of theMilky Way galaxy has the mass of 1 million suns
•Gravity so great not even light can escape

Quasars•Releases more energy thanHundreds of galaxies combined
•A trillion times brighter thanThe sun
•Thought to be matter trappedIn the accretion disc of a Super massive black hole

Exiled Stars
• Star that has escaped the gravity of their galaxy
• Slung out of a Black Hole
• Move at incredible speeds

The Unknown
For all of the stars we have seen and recorded in the Universe, over 99 percent of them are
unaccounted for
