Early Astronomy

  • Humans have been aware of night sky changes for ages
  • Early observations of planets, moon, meteors led to calendars
  • Constellations helped with navigation and exploration
  • Early astronomers didn't understand the order of the sky; cosmology was intertwined with mythology
  • Ancient Greeks separated astronomy from mythology, seeking patterns and developing a geocentric model
  • Key figures like Pythagoras, Eratosthenes, Apollonius, and Ptolemy contributed to a more complete scientific system
  • Early Greek astronomers placed Earth at the center of the universe (geocentric system)
  • Aristarchos of Samos proposed a heliocentric model of the solar system (Sun-centered), but wasn't widely accepted for centuries

Modern Astronomy

  • Telescopes allowed scientists to understand the universe
  • Galileo Galilei revolutionized astronomy by turning a telescope to the sky, ending the geocentric view and expanding knowledge of the universe
  • Powerful modern telescopes (like ESO's Very Large Telescope) can observe objects from before the Big Bang
  • Space exploration yielded a new perspective of Earth, enhancing our understanding of its place in the universe with space telescopes that observe wavelengths inaccessible from Earth
  • Space telescopes broadened views on the universe

Our Solar System

  • Mercury: Covered in craters, very thin atmosphere
  • Venus: Choked with greenhouse gases, extremely hot surface
  • Earth: Unique - liquid water oceans, oxygen-rich atmosphere, life
  • Moon: Only celestial body visited by manned missions
  • Mars: Evidence of past water, and possible surviving life
  • Jupiter: Largest planet, active atmosphere with features like the Great Red Spot
  • Saturn: Distinctive ring system made of ice and rock
  • Uranus: Large ring system, active atmosphere
  • Neptune: Furthermost planet, looks similar to Uranus, more active atmosphere
  • Pluto, Eris, Makemake, Haumea: Dwarf planets in the Kuiper Belt; numerous other dwarf planets and small objects exist in the Kuiper Belt
  • Asteroid belt between Mars and Jupiter - Thousands of asteroids of various shapes and sizes.
  • Other celestial objects - Comets; remnants of solar system's formation

Universe Structures

  • Interstellar dust and gas clouds (nebulae) exist between stars
  • Stars are born from nebulae collapses due to gravity, and die when their fuel runs out, enriching space with heavy elements necessary for life
  • Our galaxy is a spiral galaxy, with central black hole
  • Galaxies are not alone, there are hundreds of billions of them; they come in many shapes and sizes including elliptical and irregular
  • Galaxies interact, and these collisions and interactions shape the universe
  • The universe is expanding rapidly; and the universe was created in a massive expansion called the Big Bang

More Information

  • Footnotes include credits for images, data, and people, videos, and specific animations used in the demonstration
