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
How much is supermoon bigger
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)
Order of Cosmic Address
Earth, Solar System, Solar interstellar neighborhood, milky way, local group, cluster, supercluster, filaments of supercluster, universe
The assumption that the same physical laws that apply here apply everywhere with no special locations or directions in universe
Cosmological Principle
