Where We Were to Where We Are: The History of Astronomy May 19 th 2015

Announcements Your post-test will be Thursday May 19 th Today is your last day to present your 2 nd brief

Early Astronomy Questions People did not have youtube, I-Pads, phones, etc. To entertain themselves they looked at the stars

Constellations

The Zodiac Constellations

What They Thought… Geocentric Model

Why don’t we see the same constellations all year long? Clue #1 That we are not at the center of the universe

Galileo If we are at the center of the universe, how can Jupiter have moons? This was really controversial! Clue # 2 that we are not at the center of the universe

Foucault’s Pendulum Clue #3 that the Earth is not at the center of the Universe

Heliocentric Model This model put the Sun in the center of the solar system The earth rotates around its axis and revolves around the sun

Astronomy Today Today’s telescopes are much bigger, more powerful and can see in many wavelengths

This is How We Know What We Know

Fusion in Super Giants

Gravitational Collapse of a Star due to extreme pressure on the core. This stellar explosion sends shockwaves into space (gamma rays, x- rays) Supernova

Supernovas can become Black Holes or Neutron Stars Black holes – Gravity has collapsed so much that nothing can escape it’s pull, not even light Neutron Stars - Remaining core after a supernova - They are the densest and smallest stars

Astronomers Noticed a Doppler Effect

Spectroscope An instrument used to see which wavelengths of light are absorbed by specific elements known to be in space

Every Element is Different Elements absorb light at specific wavelengths of light…it is like a Fingerprint

Redshift

Cosmic Background Radiation

If Everything is Moving Away… There must have been a beginning

The Big Bang

Where We Are Most of what we know about Astronomy and Space we learned in the last 20 years In your lifetimes there will be much, much more that we understand and learn Never stop asking questions and wondering why? And how? This is how we got to where we are today
