A Universe of Stars
The Strange and the Amazing
Nebulas
THE BIG DIPPER
The Sun•Contains 99.8% of all the mass in the Solar System
•700 Million tons of hydrogen converted to helium every second
•Average surface temperature of 10,000 Fahrenheit
Our Closest Star
Mars Proxima Centauri
4.2 Light Years Away24 Trillion Miles
54.6 Million Kilometers34 Million Miles
Dwarf Stars
• Red Dwarf• Blue Dwarf• White Dwarf• Black Dwarf• Brown Dwarf• Yellow Dwarf
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
Supernova in Galaxy NGC 4526
• Supernovas can be brighter than the entire galaxy
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
