Chapter 1A Flashcards
The study of comets, moon phases, planets, nebulae, stars, galaxies, moon phases
Astronomy
Looking back about 13 billion years (400-800 million years after big bang) (10,000 galaxies)
Hubble Ultra Deep Field
Image from small part of space from Hubble Ultra Deep which compiled 10 years of previous images and shows galaxies from 13.2 billion years ago.
Exposure time is 23 days (adding 5,500 galaxies)
Hubble Extreme Deep Field
43.5 ft long and 14 ft diameter
Hubble Telescope

14%
Torus-shaped region in Solar System between orbit of Jupiter and Mars with irregular shapes
Asteroid Belt
79 moons with 4 big moons
Jupiter
Io, Europa, Ganymede, and Calisto
Supermoons from Jupiter
What is the most active of all Galiean Moons with volcanic activity
Io with bursting energy
What is the radius of the Solar Neighborhood
Neighborhood stars move with the sun in its orbit around center of galaxy
100,000 light years across and 1,000 light years thick
Milky Way Galaxy
54 galaxies (6.5 million light-years in diameter)
Andromeda, Triangulum, Milky Way
Local Group
Collection of galactic groups to thousands of galaxies
Local Supercluster
Example would be supercluster cluster (130 million LY in diameter)

Theory where electromagnetic, weak, and strong forces are merged into a single force
Grand Unified Theory
At high energy, electromagnetic and weak interaction unify to single electroweak interaction
Strong interaction and electroweak interaction unify into a single electronuclear interaction
Grand Unified Theory
Planck Era, Gut Era, Electroweak Era, Particle Era
Order of theory of when we came to be
What was the era when there was One Force
Planck Era
Era with GUT gravity
GUT Era
Era with strong electroweak gravity
Electroweak era
Gut gravity and strong weak electro gravity are what particles
Elementary particles
What era with Strong Weak Electromagnetic gravity
Particle Era where antimatter is common
Forces into existence, elementary particles, protons/atoms formed, galaxies form, stars form, we form
Theory of existence
H, He, D, Li, Be

What is subatomic particle to an atom
Subatomic particles are particles consisting of an atom like proton, neutron, and electron
