The Hubble Space Telescope
Carrie Murray NASA Top Stars, 2010
• Named for Edwin Hubble (astronomer)
• Launched in 1990
• Changed our view and understanding of the Universe.
Getting to know The Hubble
Carrie Murray NASA Top Stars, 2010
Hubble Facts
Hubble orbits 400 mi above the Earth
Orbits the Earth every 97 minute
Weighs 12 tons
Size of a school bus

How Does Hubble Create the Images?
Images come from Hubble in black and white.
Colors are assigned based on chemical elements present
Blue = Oxygen
Red = Sulfur
Green = HydrogenCarrie Murray NASA Top Stars, 2010
One image takes almost a year to create.
An image is made up of 48 separate images.

The Hubble Space Telescope has helped us understand how stars are born, age, and
ultimately die!

Eagle Nebula
500 light years away 3 gigantic pillars of
gas and dust Towers 4 light years
tall Shows the early
stages of a star Known as the pillars
of creationCarrie Murray NASA Top Stars, 2010
Our Solar System could fit inside any one of the forming stars!
Wow!!!
Fun Fact
Carrie Murray NASA Top Stars, 2010
Orion Nebula
1,000 light years away
Next phase in star development
Tiny dark spots are flattened disks of gases and dust from recently hatched “eggs”
Carrie Murray NASA Top Stars, 2010
Orion Nebula
The bright orange spot in the center gathers dust and debris from the disk eventually nuclear
fusion occurs and a STAR is BORNHeat and radiation create a stellar wind
sweeping away lose matter, but some debris remains eventually clumping together to become
PLANETS

Helix Nebula (Death of a star)
Layers of the star expand leaving behind a hot white ball of oxygen and carbon becoming a white dwarf
Carrie Murray NASA Top Stars, 2010
Supernova
Bigger Star Shorter the life More violent death Known as supernova
Carrie Murray NASA Top Stars, 2010
Every star is balanced by the inward pull of gravity and the outward pressure of heat by nuclear
fusion. Once a star runs out of fuel the pressure needed
for balance is gone.Gravity causes the star to cave in and BOOM an
explosion destroying the star and everything around it.

Crab Nebula (The Aftermath)
Expanding wreckage of a supernova that happened in 1054 A.D.
Explosion recorded by Chinese astronomers
Still expanding 3 million miles per hour
Carrie Murray NASA Top Stars, 2010
Black Hole
Created by stars 4x larger than our star
Collapsed into a single point smaller than the head of pin
A hunk of matter that is so small and gravitational pull is so strong light can't escape Carrie Murray NASA Top Stars, 2010
Astronomers noticed that stars closer to the center of a galaxy zoom at very high speeds.Most stars move around at slow speeds.
Stars being thrown around by something that is massive, but compact...
