2. Hubble Space Telescope
Launched in 1990
Orbits Earth above our atmosphere
Can “see” >13 billion light years away!

3. 1 light year… A light year is a measure of distance
The distance light can travel in 1 year
Nearly 10 trillion km
1 light year = 9,500,000,000,000 kilometers
(5,903,030,000,000 mi)
Our Milky Way is 150,000 light years across
Hubble can “see” >13 billion light years away!

4. Who Was Edwin Hubble? American astronomer (1889-1953)
First to show that the universe is expanding (Hubble’s Law)
"Equipped with his five senses, man explores the universe around him and calls the adventure Science."

5. Why a Space Telescope?
Earth’s atmosphere distorts the view of land-based telescopes
Atmosphere blocks/absorbs radiation, ultraviolet waves, x-rays… all important for viewing distant objects
Solution: put the telescope beyond the atmosphere
Hubble orbits 353 miles above Earth
One rotation every 97 minutes

18. Cone Nebula (NGC 2264): Star-Forming Pillar of Gas and Dust
Radiation from hot stars off the top of the picture illuminates and erodes this giant, gaseous pillar. Additional ultraviolet radiation causes the gas to glow, giving the pillar its red halo of light.
