Components of the Universe
All of space, time, matter, and energy that exist.
What is the Universe
The central gravitational point of our solar system
What is the Sun
The only part of the electromagnetic spectrum humans can see
What is visible light
Astronomers work this way to estimate the age of the universe
What is backwards
A large ball of gas that generates its own energy and is held together by its own gravity.
What is a star
The sun is located in this galaxy.
What is the Milky Way
Energy made up of special particles called photons.
What is Electromagnetic radiation
Everything in the universe exploded and expanded out of a single point during a single event about 13.7 billion years ago.
What is the Big Bang theory
Hot clouds of gaseous elements and compounds that serve as nurseries for stars.
What is a nebulae
This help keeps the solar system in orbit
What is the Sun's gravity
The shortest wavelengths, highest frequencies, and highest energies of the entire electromagnetic spectrum.
What are Gamma rays
The universe began as a single, tiny point - smaller than atom
What is a singularity
Millions of stars, interstellar gas, and dust that stay relatively close together due to gravitational attraction.
What are Galaxies
The amount of time it takes the Sun to reach Earth.
What is 8.3 minutes
Radiation leftover from the Big Bang.
What is the cosmic microwave background radiation
The distance light travels in one year
What is a light-year
which astronomer discovered our solar system was heliocentric?
who is Copernicus?
The Sun is made of these two elements.
What is hydrogen and helium
Wavelengths of energy that shift as objects move.
Used to detect cosmic microwave background radiation
What is the Wilkinson Microwave Anisotropy Probe
